Should "computeLiveTransfers" really take 10 minutes?

I have a reasonably unsophisticated ML application (a high-level
interpreter for the C0 programming language, a safe variant of C being
used in one of our intro courses at CMU). It takes ~15 minutes to
compile with MLton 20100608 (OSX), which I accepted as a fact of life
until I compiled with -verbose 3 the other day. I'll attach the full
output at the bottom of the email, but the hierarchically relevant
portion of the trace is this: most of the time is spent in two steps:
"toMachine" right before codegen and "computeLiveTransfers" in
codegen:
toMachine finished in 259.36 + 0.66 (0% GC)
backend finished in 267.45 + 3.29 (1% GC)
pre codegen finished in 337.52 + 46.85 (12% GC)
generateTransfers totals 558.65 + 5.92 (1% GC)
computeLiveTransfers totals 549.91 + 0.00 (0% GC)
outputAssembly finished in 602.52 + 12.96 (2% GC)
amd64 code gen finished in 602.53 + 12.96 (2% GC)
Compile SML finished in 940.07 + 59.82 (6% GC)
This was unexpected enough that I figured I'd ask if this might be a
known/unknown performance bug, and if it might have a known
workaround. Is there a good reason why these stages in particular
should be tripping us up?
Thanks,
Rob
