Re: [PATCH 4/5] exec: Remove #ifdef 0-out code for user specified exec servers.

[Roland McGrath]

There was some reason for the EXECSERVERS environment variable and I think
it might not have been just because we didn't yet have the various
translators (unionfs, etc.) that would make it straightforward to populate
a private root directory for such purposes.  But I really can't recall any
more.  Maybe Thomas would recall, but probably not.
