PR bin/48875 PR bin/51123 This adds tests more that verify fide descriptor
redirection works correctly (including that the bugs reported in those PRs
are fixed.) Note that the tests for 48875 are slow, so one of the new
test cases ends up running > 25 seconds (just doing sleeps) - each individual
test is just a few seconds, but there are several of them.
