Сигналы (Signals)
The gawk profiler accepts two signals. SIGUSR1 causes it to dump
a profile and function call stack to the profile file, which is
either awkprof.out, or whatever file was named with the --profile
option. It then continues to run. SIGHUP causes gawk to dump
the profile and function call stack and then exit.
