Hi.  Could you please try out the attached patch and let me know if it 
fixes the problem?  (The patch is relative to the 1.4 branch, I can 
send a patch based on the trunk if you prefer.)

It's probably overkill -- if a pthread_mutex_lock stub exists and does 
nothing, it's probably fine to use it, but this patch will avoid it -- 
but I'd rather get something right now and optimized later...
