I was reviewing the docs for Module Process  in WIN32_PROCESS and
found the following docs for Kill. What does signal 4-8 do and how
does it make it nicer kill. why is it 4-8 and what is the degree of
niceness as it goes along.

kill(signal, *pids)
Sends the given signal to an array of process id's. The signal may be
any value from 0 to 9, or the special strings 'SIGINT' (or 'INT'),
'SIGBRK' (or 'BRK') and 'SIGKILL' (or 'KILL'). An array of
successfully killed pids is returned.

Signal 0 merely tests if the process is running without killing it.
Signal 2 sends a CTRL_C_EVENT to the process. Signal 3 sends a
CTRL_BRK_EVENT to the process. Signal 9 kills the process in a harsh
manner. Signals 1 and 4-8 kill the process in a nice manner.

SIGINT/INT corresponds to signal 2 SIGBRK/BRK corresponds to signal 3
SIGKILL/KILL corresponds to signal 9

Signals 2 and 3 only affect console processes, and then only if the
process was created with the CREATE_NEW_PROCESS_GROUP flag.
