I hate to add to what could be an endless discussion, but... ;-)
In this case, "while" is the better time-related prefix, whether
keyword (hopeless, due to ages-old boolean-controlled loop association)
or function, since you want to imply that the code block is going
on *while* the lock is held or *while* the file is open (and you also
want to imply that afterwards, something else happens, i.e., cleanup).
while_locked(myLock):
# code that needs to hold the lock
