Subject: Re: [C/R] sleepers don't wake up on restart

I just posted v14-rc3 which includes the c/r of restart-blocks.
That should improve the situation.

However, depending on which syscalls one uses, process may still
seem "stuck" after restart because the current code still does
not save signals nor task timers; If a signal was pending (SIGALRM
for example) after freezing but before checkpoint, it will be lost.
If a timer was set at checkpoint, it will not be restored.

So depending on your program, you may still experience issues
until I add patches to handle that.

Oren.
