rts: ProfHeap: Fix wrong time in last heap profile sample
We've had this longstanding issue in the heap profiler, where the time of the last sample in the profile is sometimes way off causing the rendered graph to be quite useless for long runs. It seems to me the problem is that we use mut_user_time() for the last sample as opposed to getRTSStats(), which we use when calling heapProfile() in GC.c. The former is equivalent to getProcessCPUTime() but the latter does some additional stuff: getProcessCPUTime() - end_init_cpu - stats.gc_cpu_ns - stats.nonmoving_gc_cpu_ns So to fix this just use getRTSStats() in both places.
