Just thought of this.

A feature missing from `chroot' (unless I miss something) is that on
Unix, the root is inherited across processes.  That is important since
`chroot' is often used for security, so that no matter what the luser
does, they are confined to that directory.

Obviously we can't hope to implement that in general, since it will
require cooperation on the part of the child, which may or may not be
DJGPP-compiled.  Also, I'm not sure if it's important, since security on
MS-DOS is impossible anyway.  But I just wondered if perhaps the
application using `chroot' here (for what are we implementing this,
anyway?  I forget) will expect that.
