[John-Mark Gurney]

Author: jmg

New Revision: 285297
URL: https://svnweb.freebsd.org/changeset/base/285297

Log:
  upon further examination, it turns out that _unregister_all already
  provides the guarantee that no threads will be in the _newsession code..
  This is provided by the CRYPTODRIVER lock...  This makes the pause
  unneeded...
