Comment(by Favonia):
I quickly reviewed the code. For the new function I might prefer
{{{
OpenHandle h -> do
gh <- getProcessGroupIDOf h
signalProcessGroup sigINT gh
return p_
}}}
instead of
{{{
OpenHandle h -> do
signalProcessGroup sigINT h
return p_
}}}
if possible. The difference, as pointed out in my previous comments, is
that this will work even if {{{create_group=False}}} or the child has
changed its group. The technical problem is that {{{getProcessGroupIDOf}}}
(wrapper of {{{getpgid}}}) does not exist in Posix package now! I will try
to write a wrapper... hopefully things will be integrated into
{{{System.Posix.Process}}}.
PS: Thanks for your hard work. I wish I knew this ticket so that I didn't
have to implement this by myself. :)
