[mapserver-users] Thread safety

[Frank Warmerdam <warmerdam@pobox.com>]

Folks,

I have finished committing my thread safety work.

 o The --with-threads configure switch can be used to enable thread safety
   on Unix ... it will try to use -lpthreads.

 o GDAL has proven to be very thread unsafe because of my use of a global
   image cache mechanism.  In a multi-threaded world it is common for one
   thread to expire a cached image tile while another thread is still using it.
   So I have added a lock around GDAL.

 o I haven't implemented the thread safety stuff on Windows, but if someone
   wants it let me know.

Best regards,

--
