Oh, I'm sorry. I was referring to unfsd.

I'm not a huge fan of TIRPC either.

I agree.  It makes for trickier code though.

The premise of the "java way" of writing network services (one thread
per connection) is you trade complexity for computing resources. If
you create complex applications, you need expensive programmers and
QA. If you solve a problem by throwing more threads at it, the customer
will need more expensive hardware - which is too bad, but at least
it doesn't show up on your R&D budget :)
