Are you using the NT version of NSPR or the Win95 version ?

What is your OS_TARGET environment variable set to when you build NSPR ?

If it's set to WINNT, please try setting the environment variable 
NSPR_NATIVE_THREADS_ONLY to 1 . Otherwise, your two NSPR threads might 
be running with 2 fibers off the same native thread, which could 
potentially cause a deadlock.
