I said much the same to Jeremy when he mentioned this to me long ago in
our occasional phone calls.
As such, I strong agree, and would like to move us further towards
using GnuTLS for as much of our crypto as possible. I understand the
argument about 'working patches trump', but still don't want to be
maintaining more crypto code.
