A pane's ctl takes acme's lock and unlock
A client doing an edit of several writes to addr and data had no way to
keep another client's from landing in between. acme's window ctl takes
lock and unlock for this (editors/acme/xfid.c:603-611): a qlock that
blocks a second locker, owned by the fid that wrote it and given up when
that fid is clunked, binding only clients that ask. pardes does the same:
the open's record holds it, a second lock parks until unlock, close or
the pane closing, and no other write is refused for it.
