 It still won't always work, though.
 Since the wine people apparently believe they don't need to check for
 the feature before using it, only checking if the linker understands
 how to try, perhaps it should be disabled in binutils until we can
 come up with a complete solution.

 That has its problems, but would probably be better. Unfortunately,
 the interface has been handed to us from outside, and it came from an
 environment that doesn't have a problem with pinning half the
 filesystem permanently in the namecache.
