It is testing if the core functionality that TextMate.executor relies on is available and works in ruby 2.0.

Figure out which assumption 2.0 breaks, which is what I was trying to do by having you run the code that tests our core assumptions (creating a pipe and getting the write-end by creating a file descriptor from its integer representation).

It does look like it is being closed, though _nothing_ in the user script should close this file descriptor, so the most likely explanation would be, that ruby 2.0 closes all open file descriptors (except 0-2) and _before_ handling at_exit code.

I find this a little weird though, if they are actually doing that — should be possible to test though.
