From lib/Apache2/SizeLimit.pm:

 31 die "Apache2::SizeLimit at the moment works only with non-threaded MPMs"
 32     if Apache2::MPM->is_threaded();

Threaded MPMs make life more difficult here.  You want to eliminate
the particular interpreter that exceeds the specified size, but does
that mean you just kill the thread which the interpreter is in, or do
you restart the entire httpd process?  There is also multiplicity to
consider, which if I recall correctly is multiple interpreters per
thread.
