wanted

Run panic tasks on signal or broadcast receive.

Listen for signals:

• USR1 to increment counter
• USR2 to decrement counter

When counter equals threshold, run "arm" goroutine which waits for delay, if while delay counter become below threshold stop "arm" goroutine, else do clean and exit.

Broadcast receiver doesn't use counter.

Clean order:

• Async (Broadcast, Run, Request, Mail)
• Kill
• Remove
• Run

Async tasks has timeout, default to 16s, and run concurrently.
