Does anybody know more or less well known replacement for
"lockfile" utility shipped with procmail?

I'd prefer standalone utility that is distributed without so heavy baggage.

Unfortunately shlock cannot WAIT until lockfile is freed :-(

while ! shlock ...; do
sleep xxx;
done

looks ugly

WARNING: daemontools-0.76nb1 may not be put on a CD-ROM:
WARNING: modified source and binaries may not be distributed
WARNING: daemontools-0.76nb1 may not be made available through FTP:

Also running child process doesn't look good.
shlock's way suits my needs better.
