Bug Description
In signal handlers, there are calls to nih_warn(), nih_info() and nih_fatal(), which in turn invoke logger_kmsg(), which calls fopen(), fprintf() and fclose(), which are not signal safe.

Also, exit() is used which is not signal safe and has potential atexit() issues, _exit() should be used instead.
