I can't believe anybody else is having this problem. It hangs my machine 
if I mess in opening and closing Gem windows.

Anyway I solved it by adding:

glXMakeCurrent(info.dpy, None, NULL);

before calling glXDestroyContext in GemWinCreateXWin.cpp (line 240 in 
gem 0.90).

Now I can destroy and recreate windows without problems. Authors, please 
patch this.
