With the patch zdtm will check not only periodic timers, but also
one-shot ones.
Set one-shot timer to expire in a very long interval (INT_MAX in the
test), and check its remaining value after checkpoint/restore. The
following relationship must hold:
initial_value - remaining_value = time_passed

Here are a few bugs which hide each other.
* memcmp(&newset, &oldset, sizeof(newset) returns 0 is masks are equal.
* sigprocmask return sigset_t and it contains extra bits for the future,
so we need to initialize all this bits otherwise they will contain
random data.

The first is similar to existing snapshot test -- it calls
several pre-dumps on memory-changing zdtm test, then dumps
and check restore goes OK.
The second test is aimed at measuring frozen-time -- it
takes zdtm test with big mappings, dumps one, then start the
test again and calls one pre-dump plus dump. The sum of
frozen times in the 2nd dump (well, pre-dump + dump) should
be much smaller then the one of the 1st "just dump".

Update to patch "check: Introduce --ms option" (commit: 379abca968)
I find this error in my box:
cc -g -O2 -Wall -Werror -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -iquote ../../lib/arch/x86/include -I../../lib session03.c ../../lib/libzdtmtst.a -o session03
session03.c:112:7: error: variably modified ‘stack’ at file scope
The reason is :
"#define CLONE_STACK_SIZE PAGE_SIZE" is conflict with "#define PAGE_SIZE (sysconf(_SC_PAGESIZE))" defined in <sys/user.h>.
I think CLONE_STACK_SIZE should be seted 4096 as session02.c.

The pipe retrieving shared libraries the test depends on
ldd $test_path $ps_path | awk '/^\s/{ print $1 }'

Before this patch crtools/test is bound to crtools/test/dump/crtools.XXXXXXX
It's a main reason why "make clean" deletes all content from crtools/test.
Always when you have a test bind mount. You have a test bind mount, when
a test is executed. You execute a test sometimes. So "make clean"
deletes all content sometimes;).
This patch fixes this problem.
Actually this patch fixes more significan problem. If / is a shared
mount (it's defult in FC19),
$ mount --bind crtools/test crtools/test/dump/crtools.XXXXXXX
will recursively copy all previous bind mounts.
E.g:
cd crtools/test
make -j 4

If a master point has sid, it doesn't mean, that all slave points
will have sid. Look at tty03 for example:
PID SID TT COMMAND
26748 26748 ? tty03
26749 26749 pts/2 \_ tty03
26750 26750 ? \_ tty03
The second process has not a file descriptor for the ctl tty,
but this tty is opened in tty03.
v2: If a slave point with sid has not a master point, the option
--shell-job must be set and sid isn't restored for such terminals.
