Cyrill Gorcunov 6e4d05853d compel: infect -- Don't forget to fetch sas early 
When infecting victim we construct sigframe to
be able to self-rectore it in case if something
goes wrong. But in case is a targer been using
alternative stack for signal handling it will
be missed in sigframe since we don't fetch it.

Thus add fetching sas on infection stage and
put it into signal frame early.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
