Of course, I've written a few pretty stupid lines:

Bla-bla.
Compilation of the expression is - of course - quick.
What is slow is evaluation in specific situation:
if string's length is exceeding upper limit (32 or whatever above ~20).
Try demo (org.apache.regexp.REDemo). Enter the regexp
and then string to match: after typing last character that makes
string non-matching, re.match() lasts tooooo long.
Sorry for mystification.
