We've found that use of the internal allocators in the profiling runtime's profile collection service interferes with some custom malloc implementations (like tcmalloc). This bug tracks the work to remove reliance on the internal allocator(s) from all aspects of the profiling mode runtime for XRay.

It seems we've missed more cases of this in the profiling runtime. Reopening to track more changes.
