I have not had time to look at all the docs to see what changed, but we
have had a problem here with a multi-threaded program calling
sasl_client_init multiple times in parallel and getting crashes and hangs.
I've found various comments inside code and on the web about which
routines are vs. are not thread-safe, including that the sasl_set_*
routines are not, but I have not seen anything
that says "make sure you don't have parallel calls to sasl_client_init"
Can there be some kind of note somewhere about thread safety?
Sometime, if I have time, I will be trying to make sasl_client_init
thread-safe if possible, probably using static pthread locks (in a
library, static locks are the ONLY way to guarantee
no parallel mutex lock creation, which is a big no-no) but I got stuck
on a non-sasl customer issue which might take me a long time.
