When you download or receive mail, a second procmail may start for a
second message before the first instance of procmail has finished. Thus
there is potential for two messages to be written to your mailbox at the
same time.
To avoid this, when procmail comes across a :0: receipe, it will pause and
will not attempt to write to a mailbox if another procmail is writing to
it.
