I have narrowed this down to a problem in how ssh and select() are
interacting.  To be specific, running select() on the open ssh output file
descriptor always returns data available, but when an attempt is made to
actually read said data with read() there is no data (an error occurs).  I
do not know if this is an ssh problem or a problem with some other aspect
of the system regarding pipes.
