341N/A4614834: Xlib color functions are not MT-safe
341N/AIn a multithreaded Xlib client:
341N/A * concurrent access to XAllocNamedColor() make the client crash
341N/A * concurrent access to XLookupColor() make the client crash
341N/AThe cause of the problem is that in multithread environment some data
341N/Asame time by multi threads. Adding some lock and unlock code to make
341N/Asure only one thread can access the data at one time fixed the
