Comment 10 for bug 230877

I had a quick look at how Python's subprocess module does it; it basically uses sysconf to get the max fds, and then calls a new function "os.closerange", which is just a basic loop doing close() over the fd range.

fdwalk() seems like a Solaris-specific function? I would say let a patch for that be written/tested by someone from the OpenSolaris community if they want it.

Stylistically this patch doesn't match the rest of the code - need a space between name and function call and the for loop.

After that's fixed r=me.
