> Does the server destroys the GC contexts created once a function closes?
GC contexts are created using GrNewGC(), and are not destroyed
until the GrDestroyGC call is executed. This allows context state
information to be quickly available in the server for all draw functions,
which require a drawable (window or pixmap) and GC.

memory is freed?
When you're done using a GC for good, you'll definitely want to destroy
them, especially if the code loop calls GrNewGC again.

No. Unmapping a window just causes the server to send expose
events to all windows underneath the unmapped window. The
window structure stays around, unchanged following map and
unmap calls.
