Can't exec from a Cocoa app?

Subject: Can't exec from a Cocoa app?

I have an app which at some point wants to call execle().  However the
call fails, returning -1 with errno set to ENOTSUP, "Operation not
supported".

The execle() call is pointing to a valid mach-O binary (itself, as it
happens, and yeah it's the binary and not the bundle).  The reason I
bring this up here is that if I copy and paste the execle() call into
a plain old C command-line app (a basic sanity check done since "man
execle" doesn't even allow that ENOTSUP can happen), it works exactly
as I'd expect.  So... something about running as a Cocoa app makes
this not work?  Is there something extra I need to do to make it work
from my Cocoa app?
