Traces memory leaks
TestLeakTrace provides several functions that trace memory leaks. This module scans arenas, the memory allocation system, so it can detect any leaked SVs in given blocks.
Leaked SVs are SVs which are not released after the end of the scope they have been created. These SVs include global variables and internal caches. For example, if you call a method in a tracing block, perl might prepare a cache for the method. Thus, to trace true leaks, no_leaks_ok and leaks_cmp_ok executes a block more than once.
