This doesn't do anything in the default process-per-task mode, because
those child tasks exit using _exit(), which doesn't trigger the event
tracer destructor to flush.
I don't remember exactly why I exit with _exit(), so I'm going to have
to follow up on that. But written this way as I think I'm at least
initializing the tracing in the right place for each process for the
future.
In threaded (-j -1) and serial (-j 0) modes, everything seems to work
great.
I'm also thinking I might add a tracer like the SkDebugf tracer but
using ok_log(), which handles interlaced logging from concurrent tasks
better than vanilla SkDebugf.
Example:
ninja -C out ok; and out/ok gm 8888 filter:search=fontmgr_bounds trace -j -1
