 The "+RTS -px" is undocumented (except for appearing in the "+RTS -?"
 output, and it doesn't produce XML. Also, the allocations are printed in
 words rather than bytes, which I assume was unintentional.

 The flag is `prof2dot`.

 We should either remove or document the flag. Perhaps also rename it if
 it's not going to produce XML output (perhaps "+RTS -p --machine-
 readable"?).
