[Xglamo] crash with xcompmgr

I was playing a bit with the composite extension and xcompmgr (FSO milestone 5, kernel 2.6.28, xserver-kdrive-glamo-1_1.3.0.0+gitr9b28d998424c77fbc057dd3a022ccbb122793a52-r3). It works quite ok, but Xglamo crashes occasionaly. It is quite easily reporducible - just run xcompmgr and open a lot of applications. I was able to get the following backtrace in gdb:

#0 0x000577f4 in KdOffscreenAlloc? ()
#1 0x00050888 in kaaMoveInPixmap ()

I have found some bugs in koffscreen.c. Xglamo is more stable now, although I haven't tested it very much yet. Patch to hw/kdrive/src/koffscreen.c is attached.
