now we can use Lock() more than one in the same thread
and next Unlock() will recognize it
sample:
Lock(); // first lock -- resources locked
Lock(); // second lock -- skipped (counter incremented)
...
Unlock(); // first unlock -- skipped (because counter greater than zero)
Unlock(); // second unlock -- actually unlocking
