1) Allow a SIGUSR1 to stop profiling, so that shutdown need not be included in profiles. (The log file is not closed, so it can't be used to generate multiple profiles in one run. That could be changed, though.)
2) Add a JP_REALTIME option that does the profiling in terms of real time elapsed rather than time used for execution by the mozilla process (and in the kernel for the process). This allows profiling to detect how much time is being spent in the X server.
