Jeremy agrees that since this seems to be a time-sensitive threading issue
in GNU make it will be difficult to debug with the -d option. I am in the
process of rebuilding chunks of the package set with Fink modified to pass
-d with -j and with fink make installed. I really don't expect this to be
able to replicate the bug since the act of trying to observe it with -d
likely spoils the timings needed to reproduce it at all.
