Re: Procsub.tests on OSes using named pipes

[CHIGOT, CLEMENT]

Hi all, 

I might have found a way to avoid unkilled subprocesses when they are stuck in 
the open syscall. 
When the parent shell is killed, we can force it to open and close all the 
named pipes that it still have. 
It might be a bit harsh, but at least there is no unkilled processes anymore. 

It might also fix your case, Chet. Though I haven't checked.

I'm currently checking if it's working correctly on daily uses. And if yes, 
I'll submit the patch to see if it can be merged as is. 

Sincerely,
Clément
