I agree. That's why I am (and OSF is) an advocate for a standard threading
interface with a portable implementation.
I might say:
Of course, Sun RPC has gotten by (or maybe not gotten by :-) for
years with limitations of this sort (and more). E.g., if you use
Sun RPC over UDP/IP, you're limited to 8K worth of data and the call
semantics are unpredicatble. "Use Sun RPC over TCP/IP", you might
say. Oh well, then the number of concurrent calls I'm allowed to
have is limited by the number of TCP connection I can (effectively)
have open at a time. Seems like a pretty arbitrary limitation to
put on a distributed applications programmer. The load of having,
oh, 100 clients doing lightweight things may be low. It's just the
poorly chosen requirement the RPC package made on the system that's
preventing me from doing what I want.
But I wouldn't want to compare NCS to Sun RPC :-)
