Kristoffer Dalby 3ebe4d99c1 mapper/batcher: reduce lock contention with two-phase send
Rewrite multiChannelNodeConn.send() to use a two-phase approach:
1. RLock: snapshot connections slice (cheap pointer copy)
2. Unlock: send to all connections (50ms timeouts happen here)
3. Lock: remove failed connections by pointer identity

Previously, send() held the write lock for the entire duration of
sending to all connections. With N stale connections each timing out
at 50ms, this blocked addConnection/removeConnection for N*50ms.
The two-phase approach holds the lock only for O(N) pointer
operations, not for N*50ms I/O waits.
