[OS X TeX] Strange network behavior with XeTeX

[James Crippen]

When I run XeTeX (actually XeLaTeX) on a document I get some strange
network usage happening. I'm at home on a PowerBook G4 connected over
wireless to my home network. There is a G5 which has a USB printer
attached to it and which is served by the G5 to the network. On my
laptop I check the access_log for cups at /var/log/cups/access_log and
see this:

localhost - - [13/Sep/2006:19:37:57 -1000] "POST / HTTP/1.1" 200 152
localhost - - [13/Sep/2006:19:37:57 -1000] "POST / HTTP/1.1" 200 152
localhost - - [13/Sep/2006:19:37:57 -1000] "POST / HTTP/1.1" 200 75
localhost - - [13/Sep/2006:19:37:57 -1000] "POST / HTTP/1.1" 200 219
localhost - - [13/Sep/2006:19:37:57 -1000] "POST / HTTP/1.1" 200 231

and at the same time I'm getting a huge wad of network activity. This
stalls XeTeX for a good minute while data is transferred over the
network. I haven't traced it to see what is going on, but I can if
necessary.

Any idea why XeTeX would be causing this behavior?
