Eduardo,

This causes MapServer to use pthreads libraries to enable thread locking
and per-thread error management.  Without it multi-threaded applications
of mapserver (such as when loaded as a PHP, perl or Python module in
Apache or when using FastCGI) are likely to cause various ugly crashes.

Some more information can be found at:
  http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?ThreadSafety

I would note that I don't consider mapserver to be thread-safe even with
this all enabled, but it should be close for simple cases.

Best regards,
