I'm not familiar with callgrind -- I've had both results with both "perf
record" and gprof.  But yes, callgrind should be fine.

I need to find out where the CPU time is going.  I suspect either the
quadratic loop in xroute.c, or linear-time route selection in route.c.
I intend to fix both, but I'd like to be sure.

Ok, I'll see on Monday if I can get an extra VM before Christmas.
