Actually, you can (unless it is _very_ weirdly written.)  The multiplexor
performs all the magical process-pool-management so that individual
filters do NOT have to be reentrant or thread-safe.  The only time issues
arise is for deliberately-shared resources like a database file, in which
case you must use locking to ensure exclusive access.

Within a given Perl process, the filter will _never_ be interrupted.  Your
filters do not have to be reentrant.
