Thanks for the report. Actually it has been noted before that the (currently) last test in S17-supply/start.t fails occasionally (cmp. http://irclog.perlgeek.de/perl6/2015-02-08#i_10078057 or Raku/roast@ee6df08125).

There are a few of those "flapping" tests, which pass most of the time, but not always. However, I have updated the subject of this ticket and we'll keep it open until the underlying problem is fixed.

Best regards

Christian

Thanks for the report. Actually it has been noted before that the

time, but not always. However, I have updated the subject of this
ticket and we'll keep it open until the underlying problem is fixed.

Since this ticket was last considered, many stability fixes have been made, and so far as I know all concurrency tests are now stable. I've not seen this particular one fail in a while; I also just did 100 runs of it on a loaded system and it passed every time. So, unless we see it fail again, I think we can consider this one resolved.
