Okay, with gpilotd and the applet dead, I run "pilot-xfer -p usb: -l",
and strace (attached) gets to the "futex(... NULL".  Then I hit hotsync
on the 700p, and pilot-xfer goes up to max CPU but with no further
strace output.

Then I do "gdb pilot-xfer" and "run -p usb: -l", wait a bit, and again
the pilot-xfer process goes to max CPU.  Hmm, oh well, no debugging
symbols, this is Debian. :-(

I can try rebuilding pilot-link with dh_strip removed, but don't have
time now.  Does the strace output help?
