I figured out this happens only if something was run from bash. For
example, irssi. If disconnection occured when there was only bash
active, it does not become <defunct> but stays forever with flag 'I'
in processes.

Since cygwin1.dll version 1.5.20 I get bash processes became <defunct>
sometimes after SSH session disconnects. For example, today there was
a network problem and my SSH session got broken, after I reconnected,
there was 1 <defunct> process. Sometimes this does not happen. All
components I am using are updated to latest release available.
This is something to show what is happening:

pslist is /d/tools/bin/pslist
I also want to mention that before 1.5.20 bash processes just remained
in memory and I had to kill them manually. It would be much better if
they'd got killed upon SSH disconnection, like it happens in normal
unix environment.
