Details - in a multi-threaded application which does a lot of
gdImageStringFTEx()ing, lock contention on gdFontCacheMutex
degrades performance.

removing the mutex, and using a per-thread cache and library,
improves performance by 2x (in our application, your mileage may vary).

patch for gdft.c attached.
