* made the request counter a package's private lexical variable, since it shouldn't be accessible by other modules.

* improve the debug mode testing whether at least one threshold was set
* cache the previously fetched shared and/or size for reuse in the unshared memory calculation, which makes things a bit faster.
* update docs
* making the DEBUG a constant variable, settable via PerlSetVar
* A few code style changes and doc fixes
