oh duh!

let me update

hrm...

when wcopen() is called, we call vt_open() which on the first open calls tem_init() which stashes the queue_t passed in from wcopen()

however wcclose() doesn't call vt_close() if the minor# is 0, which means that queue_t stashed by tem_init() is never cleared

and i'm not sure why we're explicitly skipping this for 0

or if maybe the tem_cleanup should move from vt_close() to vt_clean()
