(Firefox :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9b3pre) Gecko/2008020404 Minefield/3.0b3pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9b3pre) Gecko/2008020404 Minefield/3.0b3pre

When firefox launches external apps on linux the child process will have lots of redundant file descriptors open, even the sound device etc.

I have verified this bug using minefield from feb1 running on ubuntu gutsy.

Reproducible: Always

Steps to Reproduce:
1. open a youtube video and let it play
2. run "fuser /dev/snd/*" and verify that firefox's pid is using the sound device
3. open a PDF file (so that it starts in evince or kpdf or any external app really)
4. re-run "fuser /dev/snd/*" and notice that the PDF viewer is now using the sound device as well
