again: multithreaded processes stucks in the STOP state

[Oleg V. Nauman]

	Nothing changed in the fresh RELENG_5 - multithreaded processes
continues to stuck in the STOP state.
	After today's upgrading to the fresh RELENG_5 clamav-milter continues
to stop responding. I tried with and without procfs mounted, nothing
changes.
	There is two ps output (with and without procfs mounted) after
kill -CONT (sorry for bad formatting and long lines):

ps -O flags,ktrace,lockname,mwchan,nwchan,sig,sigcatch,sigignore,sigmask,state,wchan,xstat 422
  PID       F   KTRACE LOCK   MWCHAN NWCHAN    PENDING   CAUGHT  IGNORED  BLOCKED STAT WCHAN  XSTAT  TT  STAT      TIME COMMAND
  422  288180        0 -      -      -           40000 10040000  87a9001 fffefeff TLs  -          0  ??  TLs    0:02.02 /usr/local/sbin/
ps -O flags,ktrace,lockname,mwchan,nwchan,sig,sigcatch,sigignore,sigmask,state,wchan,xstat 424
  PID       F   KTRACE LOCK   MWCHAN NWCHAN    PENDING   CAUGHT  IGNORED  BLOCKED STAT WCHAN  XSTAT  TT  STAT      TIME COMMAND
  424  288180        0 -      -      -           40000 10040000  87a9001 fffefeff TLs  -          0  ??  TLs    0:01.73 /usr/local/sbin/

	clamav-milter doesn't have any gdb attached to him

	This is a real showstopper for 5.3-RELEASE, I think. In this
situation I will be not use 5.3-RELEASE in the production environment.
