My 2 cents:
- The problem is not keeping the file descriptors open after a fork, but after an exec.
- There are a lot of valid reasons to keep file descriptors open after a fork
- There are a few valid reasons to keep file descriptors open after an exec, but I don't think any of these reasons are in the scope of a browser
- Modifying ForkAndExec() behaviour in nspr means a change in behaviour in all applications using NSPR, which may or may not expect file descriptors not to be closed.
- As you pointed out, nowadays GIO and GnomeVFS is used (except for mailcap entries), but I don't think they close file descriptors either.
