The initial key exchange and session key negotiation will be slow, but I
get acceptable performance out of my 486-33.  Mine only has 8Mb, so isn't
suitable for running more than two or three ssh sessions at once, but
with 32Mb it should be more than enough.

Ah, I thought it was integer-only.  If I can be bothered, I'll
grep float the_sources.
