>Description:
	I upgraded my laptop from a November 22 build to January 1/2,
	and Mozilla and other applications suddenly fail.
	The last few lines of kdump are:

  1401 mozilla-bin CALL  __sysctl(-1077943464,2,-1077943472,-1077943468,0,0)
  1401 mozilla-bin RET   __sysctl 0
  1401 mozilla-bin CALL  mprotect(0x4b601000,0x1000,0)
  1401 mozilla-bin RET   mprotect 0
  1401 mozilla-bin CALL  sa_stacks(0x10,-1077943248)
  1401 mozilla-bin RET   sa_stacks 16/0x10
  1401 mozilla-bin CALL  sa_enable
  1401 mozilla-bin RET   sa_enable 0
  1401 mozilla-bin PSIG  SIGSEGV SIG_DFL
  1401 mozilla-bin NAMI  "mozilla-bin.core"

>How-To-Repeat:
	Run November22 kernel/userland.  Mozilla works.
	Upgrade to Jan1 kernel/userland.  Mozilla coredumps.
