It probably isn't anything ls is doing. It's probably just the open
of whatever shared libraries ls has in common with the shell running
in the other window.
And so, on a long-running system with frequently-accessed binaries (or
just shared libraries) mounted over NFS, where it's unlikely that all
descriptors will ever be closed at the same time, a hang/crash/failure
essentially becomes inevitable?
Is this a solvable problem? (Outside of oneopenown.)
