I'm running a 486/33 with 16 MB of RAM and a huge stinking swap file.  I've
tried it with no other applications running and I've gone over the .ini file
several times.  This is frustrating...

Sorry for the clichi, but I have to say:  NOT!  Windows apparently was running
low on resources, so I had to reboot (after two IVC GPFs).  I'm up again for
the moment, so if you'd like to try (again?), the number is 128.83.128.80.

Thanks again for your help and your patience!

It still lacks the multitasking features that SCSI has. Under a true multi-
tasking OS like UNIX, OS/2 or NT, SCSI can make a big difference.

Load an ASPI driver and compare. Probably little difference. Now try comparing
a SCSI based system with multiple devices (disks, tapes, CDROM) on a true
multitasking OS like NT or OS/2 against an IDE drive, and see which one is
faster.

After a TCP socket receives a reset--at initial connection attempt
or while connection is active--you still need to call closesocket().
You always need to call closesocket().  This function "releases the
socket descriptor", and any associated resources (e.g. memory allo-
cated for WinSock internal socket structures).  This requirement is
*not* implementation dependent (i.e. it's universal).

You need not call shutdown() after receiving a reset, though
it shouldn't cause a problem to do so.  It may fail with the
WSAENOTCONN error, though this *is* implementation dependent.
It might not fail, or it might return a different error.  Even
though they're not listed for shutdown(), it would be legal for a
WinSock to report either WSAECONNABORTED or WSAECONNRESET errors
after such a failure from shutdown() (see section 3.3.4 Error
Handling on page 16, for the caveat in the last paragraph).

After the other side initiates the graceful close of a connection,
you need to call closesocket() (or shutdown()) to complete the
close.  Unlike when your side initiates the close, in this case
calling shutdown() before closesocket() should not be necessary.
Because the other side already sent a <FIN>, you know they won't
be sending any more data, and the main reason to call shutdown()
(with "how=1") before closesocket() is to read any remaining data
before releasing the socket.
