registry keys.

ctrl_dir otherwise. Each node's spy socket has a unix filename.
This is done since it is expected the temp directory will be on the local
file system (which will allow special files to be created).

log spy socket error (just break loop).

block size average).

block size average).
Removed unused "reserved" members (we don't mix DLLs from diff versions).

unused (passing NULL).

[untested]

something like this.

max_inactivity (seconds) - reversing Deuce's last change.

SMTP_AUTH_VIA_IP option (defaults to off).

(pth) since incom() blocks here.

Makes the poll/yield loops unnecessary.
Must use recv (not read) on sockets!

Makes the poll/yield loops unnecessary.

Removed another YIELD()-after-select() and switched another if !available YEILD() to "wait up to one ms for availability"

immediately.

one millisecond for data to become available.

for up to 10000 byte blocks from external programs with plenty of room for
telnet IAC, CRLF, or color-code expansion. Win32 named pipes, for example,
will send up to 8096 byte blocks (before CR to CRLF expansion).
Size of Win32 named pipes now specified (override 4K default).
Using WaitForSingle/MultipleObject now to detect terminated processes
(rather than looping on GetExitCodeProcess with sleep/yield).
Using WaitForMultipleObjects to immediately continue loop on remote input
(terminate 100ms wait) - experiments with local output_event (set by
sbbsexec.dll on writes) yielded no perceived performance improvement
(and named pipes, for example, would not benefit from such a mechanism).

Using inkey() timeout instead of YIELD in cold-key loop.

Baja inkey and inchar functions now use an inkey timeout of 1ms.
