Details

The SIGTERM signal should be handled "gracefully" by programs that receive it, i.e. they should not break. At present, if we send a SIGTERM to the profiler while it is writing a file to disk, the file is truncated - leading to an invalid profile file.

This was discovered while working on Bug 1883903, which initially uses SIGTERM to kill a firefox process that has timed out. As we are now trying to gather profiles when firefox times out, this SIGTERM is in fact interrupting the profiler.
