is there a known problem with named pipes in -CURRENT?

The following shell script freezes a machine in several minutes and needs
a power cycle.  You can see the increasing memory in vmstat -z (unpcb) and
netstat -u.  The kernel is FreeBSD 5.1-CURRENT Tue Nov 4 14:08:23 CET 2003.



for i in `jot 50000 1`; do
   mkfifo ${FIFO}
   echo blubb > ${FIFO} &
   kill $!
   rm ${FIFO}
