Switch to Sun's compiler or change to newer version of gcc.  I ran into
this problem with an older gcc.  When I stepped through mimedefang with a 
debugger, I found it wasn't doing "errno != EDADF" check.  If another
thread already was using that particular working directory, the program
wouldn't loop to try a different directory name.
