There are three distinct groups of possibly relevant threads, to do
with interactions between ssh-agent and one of
  ServerTree [no idea what that is]

Also, if (my own case), I use gpg-agent maskerading as ssh-agent, and
_it_ has the 100% problem sometimes.

Of course, none of this is relevant if the OP's problem with ssh is
not co-occuring with ssh-agent chewing up an entire processor.
