Description:
------------
The PCRE extension does not document that compiled regular expressions are cached internally.  I was about to file a bug requesting support for this, and thankfully decided to peak at the code before I did so.  The documentation should note this feature so that performance-minded folks can sleep better at night.  :)

This is already documented: "This extension maintains a global per-thread cache of compiled regular expressions (up to 4096)."

The cache exist, but provided by PHP.
