Try amallinfo and mallinfo for system level information about heap allocation
and shared-arena allocation.

If you are using the DEBUG version of libpf.so (2.4 or later), you can call
pfMemory::getArenaBytesUsed to inquire the exact number of bytes currently
allocated on the Performer shared arena. This number is helpful for
distinguishing memory leaks from memory fragmentation. getArenaBytesUsed
returns a valid number only in the DEBUG libraries for performance reasons.
