Bryan C. Mills e57350f4c0 runtime: fix _cgo_yield usage with sysmon and on BSD ... There are a few problems from change 35494, discovered during testing of change 37852. 1. I was confused about the usage of n.key in the sema variant, so we were looping on the wrong condition. The error was not caught by the TryBots (presumably due to missing TSAN coverage in the BSD and darwin builders?). 2. The sysmon goroutine sometimes skips notetsleep entirely, using direct usleep syscalls instead. In that case, we were not calling _cgo_yield, leading to missed signals under TSAN. 3. Some notetsleep calls have long finite timeouts. They should be broken up into smaller chunks with a yield at the end of each chunk. updates #18717 Change-Id: I91175af5dea3857deebc686f51a8a40f9d690bcc Reviewed-on: https://go-review.googlesource.com/37867 Run-TryBot: Bryan Mills <bcmills@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>		2017-03-09 18:36:49 +00:00
