Has anybody implemented file locking via shell scripts?

I need an effective way to allow multiple hosts to collect some data
locally and then dump it into a structured repository shared via NFS, which
means I will nead some form of file locking.

I would like to avoid race conditions from statements like the following:

[ ! -f $REPOSITORY/.lockfile ] && touch $REPOSITORY/.lockfile &&
MergeRepository && rm $REPOSITORY/.lockfile

Any ideas?
