Oran Agra c8452ab005 Fix unstable tests on slow machines.
Few tests had borderline thresholds that were adjusted.

The slave buffers test had two issues, preventing the slave buffer from growing:
1) the slave didn't necessarily go to sleep on time, or woke up too early,
   now using SIGSTOP to make sure it goes to sleep exactly when we want.
2) the master disconnected the slave on timeout
