Self-reply: Or is it possible that Parsec2 is so much faster that it
doesn't even show up in the .prof results?
+ The largest cost center in the Parsec2 results is the EQ2Parse
+ The largest cost center in the Parsec3 result is the Parsec function
"manyTill", which (in the prof results) is only called by "until" in
Which is consistent with my previous reasoning, at least.
