Description Jamey Sharp 2006-05-23 05:30:09 UTC 
Currently XCB will dereference a null pointer if the XC-MISC extension is absent
or doesn't work and a new batch of XIDs is needed. Probably it should return an
invalid XID instead (anything >= 2**29 should work, including -1). This behavior
then needs to be documented so programmers realize this can fail.

Latency-hiding the XC-MISC request when we're nearly out of XIDs might be a
feature too. Some API design thought should go into this: ideally it would be
under the control of the application if desired, happening automatically if the
application doesn't take care of it.
