This sounds like some program is running from /usr - do you have
/usr/bin/bash as your shell? In that case bash is removed from the
directory tree, but it stays on the disk as it might still be needed for
demand-loading. This also would explain the error 16: EBUSY, which just
means that some file on the fs is still in use.
