Comment (by brucedechant):

 The minimum thread model supported by the MapGuide server is
 FdoThreadCapability_PerConnectionThreaded because
 FdoThreadCapability_SingleThreaded impacts the server performance
 significantly due to having to block all the server's threads using the
 single threaded provider. The current server core is not designed to
 restrict this type of provider threading and therefore the minimum
 FdoThreadCapability_PerConnectionThreaded is now enforced.

 My suggestion is to make the GDAL provider thread safe so that it can work
 within a multi-threaded server.
