That's what I thought you meant, fear not :-)

Hmmm... locking can be done with... with... dang! It's not in the base

I remember there being a neat little command for doing locking in
scripts. It was called "lock" or "lockfile" or something, and had flags to
lock and unlock, and accepted an inode to lock on as a parameter.

It also had a third option, which created the lockfile, and put in it the
maximum number of locks that could be had on it at once, semaphore style.

The .BEGIN and .END targets would be the plcae for this to be run, but if
we don't have it, then that is a more interesting problem.

Thrilling, if somewhat thick reading :-)

I find /usr/share/misc/usb_hid_usages more fascinating:
