6 | # this noop trick initializes the STDOUT, so that the TAP::Harness |
7 | # issued IO::Select->can_read calls (which are blocking wtf wtf wtf) |
8 | # keep spinning and scheduling jobs |
9 | # This results in an overall much smoother job-queue drainage, since |
10 | # the Harness blocks less |
11 | # (ideally this needs to be addressed in T::H, but a quick patchjob |
12 | # broke everything so tabling it for now) |
