I've got a few tips beyond those in the FAQ, but haven't had a chance
to write them down anywhere.  If anyone wants to volunteer to write
this up, I think it would be worthwhile putting them in a web page for
future reference.

One tip:  in recent versions of R (but hopefully not in 1.8.1), gdb
always traps on a few memory allocation errors during startup.  This
is irritating but harmless, continuing from that point on will
eventually get R to start.
