Well, the signal handlers aren't cake either, but it doesn't make sockets
any more compatible, methinks...

Does it mean that if I want to port a package, which unfortunately uses
bith file IO (read/write vs. fread/fwrite :-) and sockets -  I'll have
to browse manually all the source, checking every occurance of write,
and if it looks like socket - changing it to send/recv?   Possible,
of course, but not nice at all, especially for real big packages.

If by X you mean some X-clients - then it's not a big deal (isn't
worth of reporting to the Net anyway :-).  But if, otherwise, you
mastered Roell's X11R4 with ESIX sockets - I'm absolutely SURE  a 
lot of people would like to hear more about it (and me among them).

Just can't but ask: how did you guess the additional parameter 
("struct t_call *tcall"), and _where to put it to_? I don't
think BSD manual tells you anything about it, nor SysV
books, when it comes to listen(), or accept()...

Also,  I always thought that compatibility was "invented" to let you
to keep "a little effort" as little as possible - preferably to zero.
Otherwise - it doesn't sound too hard to convert sockets-using thing
to TLI too...
