i#2601: fix thread exit race on attach (!2605) · Merge requests · DynamoRIO / dynamorio

Merged Derek Bruening requested to merge i2601-attach-race into master Aug 09, 2017

To handle a thread exiting on attach, adds a timeout to wait_event() and its corresponding implementations: os_wait_event() on Windows and ksynch_wait() on UNIX. Uses the timeout to check whether a thread exited, and if so, to move on.

Augments the test from #2600 (closed) to test this race.

Fixes #2061 (closed)
