------------------------------------------

Pavel,

Yes, Its functionality is switched off by default currently and shouldn't harm anything (at least I hope so :) )
Could you please commit it?

> There are several problems in DRLVM with native memory usage. For example:
> - Native memory usage couldn't be monitored currently in details via java.lang.management functionality
> - No explicit way to replace system native memory allocator to other memory managers in order to improve performance or footprint
> - Too many variants of the native memory allocations in DRLVM
> - Poor memory usage control (like leaks, double free calling, etc.)
> - Potential crash in diagnostics when OutOfMemory occur
> - Frequent native memory usage could cause OutOfMemory if GC wouldn't be timely called
> - No detail trace for the native memory usage
> Adding of some functionality to solve these would be hepful I think?
