*sigh*

Get rid of startup.h kludge but makeing YIELD() an empty macro in nopen and
getuserdat

*blush*

Of course, Win32 could use a real yield *hint hint*

NOTES:
------
startup.h has an ugly YIELD kludge in it, and includes both ringbuf.h and
threadwrap.h.  However, it is sometimes used in non-threaded utils.
This must be fixed!

wrapper... so just use fcntl() locks.  Also, if it is flat out impossible
for anyone to ever get a lock on a particular file (ie: is a socket) do not
fail.

Note: This trick may come in hady for a future locking solution.

this:

Whever a user connects to a node, the unix domain socket localspy.sock is
create in the node directory.  This is a RAW connection to the users data
stream.  This is NOT a telnet connection.  Do NOT telnet to the UDS... you
will not like the results.  However, you can easily and safely do something
like:

cat /sbbs/node1/localspy.sock

Possibly netcat will allow you to remote control a users session... not
sure if nc supports unix domain sockets or not.   Have fun with this one.
