  Description     : Utility for looking for perl objects that are not reclaimed.

Devel::Leak has two functions NoteSV and CheckSV.

NoteSV walks the perl internal table of allocated SVs (scalar values) - (which actually contains
arrays and hashes too), and records their addresses in a table. It returns a count of these
"things", and stores a pointer to the table (which is obtained from the heap using malloc()) in its
argument.

CheckSV is passed argument which holds a pointer to a table created by NoteSV. It re-walks the
perl-internals and calls sv_dump() for any "things" which did not exist when NoteSV was called. It
returns a count of the number of "things" now allocated.
