Revert 83784 adding functools.lru_cache() to the re module.
The problem is that the re module is imported by sysconfig
and re needs functools which uses collections.OrderedDict()
but the _collectionsmodule.c code is not yet constructed
at this point in the build.
The likely best solution will be to include _collections
as part of the static build before the rest of the
boot-strapping.

- The default size of the re module's compiled regular expression cache has been
increased from 100 to 500 and the cache replacement policy has changed from
- simply clearing the entire cache on overflow to forgetting the least recently

applications that use a lot of regular expressions and limits the impact of
the performance hit anytime the cache is exceeded.
