Lock disposal of separate gdi+ objects under different threads since this prevents malloc heap corruption seen under Ubuntu 10.04.1 and 11.04 - probably a libcairo issue
In testing, it appears that if multiple threads dispose of separate GDI+ objects simultaneously,
the native malloc heap can become corrupted, possibly due to a double free(). This may be due to
bugs in the underlying libcairo used by mono's libgdiplus.dll on Linux/OSX. These problems were
seen with both libcario 1.10.2-6.1ubuntu3 and 1.8.10-2ubuntu1. They go away if disposal is perfomed
under lock.
