Description

runtime: retake P if syscall running more than 10ms Problem: In the case of a P blocking on a syscall, with other Ps idling, sysmon can get stuck in its loop until a GC occurs. This means that the process wakes up 100 times a second in an otherwise idle process. This solution may just be hiding another issue, or even be the cause of another problem; my understanding is too limited to tell. Fixes issue 6673.
