Hm, I wouldn't limit the mechanism prematurely. Using Valgrind as an example of an alternate user of this mechanism, it would be useful to use a pipe to transmit out-of-band information from an exec-er to an exec-ee process. At the moment there's a lot mucking around with execve() to transmit enough information from the parent valgrind to its successor.
