On a slightly related note, I need file redirections to work over exec -
if only for debugging purposes.  I'm referring to line 389 onwards of
exec.c of course, where all the file handles get closed.

In the past, I've locally modified this file.  I know this is tricky to
resolve, for precisely the reasons in the comments; I'm tempted to add
an application specific variable to leave them open in specific
application cases.
