But .., any process found in /proc is not a cygwin processs?
If it isn't why ps -ef reports it?

$ ps -ef
    UID     PID    PPID  TTY        STIME COMMAND
    k        4804   4908  pty0     18:18:29 /cygdrive/c/WINDOWS/system32/notepad

In this case notepad, is a child of bash (pid 4908). So it seams a
cygwin process, isn't it?


Thanks a lot again.
