[Xcb] How come there is no xcb_free_id()?

[Bart Massey]

Not sure what you're asking here. A long-running X client that
consumes a lot of xids will eventually run out of the ones initially
allocated to it by the server. At that point, it needs to either
reclaim some of the ones it allocated previously that are no longer
valid on the server side, or get a fresh allocation. There are at most
500M possible XIDs, so it is conceivable on a busy X server that it
would eventually run out if it just kept handing fresh blocks to
applications all the time without trying to reclaim them. So...yeah.
