[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Matthew Barnett]

Matthew Barnett <python at mrabarnett.plus.com> added the comment:

issue2636-20101224.zip is a new version of the regex module.

Case-insensitive matching is now faster.

The matching functions and methods now accept a keyword argument to release the GIL during matching to enable other Python threads to run concurrently:

    matches = regex.findall(pattern, string, concurrent=True)

This should be used only when it's guaranteed that the string won't change during matching.

The GIL is always released when working on instances of the builtin (immutable) string classes because that's known to be safe.
