Cool; I'll check it out.

Ok, that code helps a lot. I see that you use wrapped calls writev() and
readv() to communicate with the socket. Using writev() gets rid of the
broken pipe error and I successfully write my connection initiation
request to the X server. But calls to readv() after I do the select +
usleep loop you suggest here just give me garbage data. (read-char) gets
#<eof>.

Thanks to everyone for their help. I feel like I'm close to figuing this
out, but I probably need to take a break from this for a
while. Hopefully I'll get this working at some point in the relatively
near future!
