Subject: Properly handle pthread_cond_timedwait timing out
X-Git-Tag: release_0_10_0~52
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=514f7a277473a79fd42303f128379792a4667e65;p=qemu.git

Properly handle pthread_cond_timedwait timing out

pthread_cond_timedwait is allowed to both consume the signal and
return with the value indicating the timeout, hence predicate should
always be (re)checked before taking an action
