This fix doesn't seem to work on 9.1 i386, as the new FreeBSD test introduced in this PR hangs 90+% of the time.

SIGCANCEL is the signal used by pthread_suspend_np internally.
The signal handler already deal with being in critical regions, hence it
doesn't suffer from the deadlock. As it isn't allowed to overrride SIGCANCEL we
imitated the behavior by poking in pthread guts (THR_IN_CRITICAL).

Any further details? It doesn't seem like the pthread layout changed from 8.x to 9.1. Is it easy to reproduce w/ the test case of comment 5?

Sorry, only seeing your question now. I was simply checking the D tests on FreeBSD back then but I haven't used that OS in years, so can't look into it further now.
