Description

Add assertion checking in sysMalloc to try to catch when malloc overlaps allocation with a portion of the virtual address space that MMTk things is in the Java heap.

In general, need to make address space management bulletproof so that we don't hand out the same piece of memory to two different people...

In the process of porting native threads we (Daniel and I) introduced something like this. It's not an assertion but rather a warning, but it does the job most of the time.
