Subj : asynchronous cancel vs calling pthread_exit in signal handler

I'm a newbie in MT programming and I've been reading PwPT about
cancelling the execution of a thread.

I'm writing a database application which calls some 3rd party library
to send SQL queries to the database but sometimes the database is not
responsive and I would like to interrupt the call. Sending a signal
doesn't interrupt the call every time so I would like to
cancel/terminate the thread (deferred cancel doesn't work either).

>From what I've read it seems that asynchronous cancel is definitely
something that I shouldn't use. but I came across a suggestion of
calling pthread_exit() in the signal handler, I wonder if that's just
as dangerous as using asynchronous cancel?

Any help is appreciated. Thanks in advance.
