Fix overflow caused by default spin timeout (backport #1563)#1568
Conversation
Previously the max() value of the steady time was used as the default deadline. In some environments this results in overflows in the underlying pthread_cond_timedwait call, which waits for the conditional variable in the events queue implementation. Consequently, this lead to freezes in the executor. Reducing the deadline significantly helped, but using `cv.wait` instead of `cv_.wait_until` seems to be the cleaner solution.

Description
Previously, the max() value of the steady time was used as the default deadline. In some environments this results in overflows in the underlying
pthread_cond_timedwaitcall, which waits for the conditional variable in the events queue implementation. Consequently, this lead to undefined behavior and freezes in the executor. Reducing the deadline significantly helped, but usingcv.waitinstead ofcv_.wait_untilseems to be the cleaner solution.Did you use Generative AI?
