Hi
Yes, that's actually a pretty good idea, to use it as a test case.
Just try to scramble up a few K's or M's of data and run through it and see
what happens.
As for creating it all the time... Are we using Java regexps for this, btw?
If we are, then it would make sense to compile a regexp the first time you
find it and and then save
it around somewhere for a while. Probably a space-limited Map with the
regexp-string itself as key would probably do it. Not a very big thing to
implement either, probably.

Bummer, I was hoping the each in yaml_spec was one culprit. I realize
now that it is just a gigantic mult-line string. No yaml at all.

Those regexps should not be slow in Java since they are all rooted
to front and back of line. Also they all are only working on a single
line at a time. Though I think we are constantly reconstructing them
and maybe that is the slow part?
I will take a look this weekend a bit too just to get a handle on this.
This particular code seems pretty isolated (as in it could make a good
test case on a large data set -- good benchmark perhaps?).
