As far as I know, this is not a threaded application.  (I'm writing most
of it from scratch and not using threads.)  I am using an embedded perl
interpreter though, of which I am suspect.  Whenever I connect to my
process with gdb I see messages like this:

[Thread debugging using libthread_db enabled]
[New Thread 1084529568 (LWP 7654)]

LWP, perhaps only coincidentally, is the name of a perl module I'm
using.  I don't remember getting this message about threaded debugging
before I plugged perl in.  My problem is happening between perl routine
invocations.  each perl routine seems to block though, so I didn't think
threads were a possibility.

Do you have advise for me about how to test for threads being the source
of my problem?  The problem doesn't happen reliably right now, so I
can't trust a solution that might just hide the problem.

Thanks very much!
