recomp013

[Simon Peyton-Jones]

I lied.  Whether or not the 'sleep' is there, the test usually fails, but occasionally (one time in ten or so) succeeds.

| | It works here. So that means either two things:
| |  * that the bug described in #8247 is actually present in HEAD, but
| |    only under certain circumstances, or
| |  * that there is a timing issue with the update of B.hs.
| |
| | The latter seems to be more likely. I notice that other recomp-tests
| | have a "sleep 1" before updating the file: If you insert that in
| | recomp013/Makefile, does it go through for you?
| |
| | Greetings,
| | Joachim
