Comment:

 I've talked to David a bit about this, and I do think it's a good way to
 run performance testing on private networks. It could also IMO make Shadow
 output easier to analyze, if the two facilities can be made to cooperate.

 Preliminaries:
   * We should do a little research to make sure that there isn't some
 other important userspace instrumentation API that we should keep in mind
 for maintaining compatibility with.  So far, it doesn't look like there
 is.
   * This should be, as noted above, controlled by a compile-time and a
 runtime option; both should be off by default.
   * We should make sure to document that this is for researchers and
 developers, not something that you should be running on a live relay.
