No it's hanging in heurisch.
(And in fact smichr already merged my fix - i.e. turning the test into
skip.)

Hmm. From what I remember, it was not hanging in the new algorithm,
but in heurisch(). This means that it probably would indeed finish if
you let it run long enough, but that algorithm can be so inefficient
that there's no telling if it could be hours, days, weeks, ...
If it is indeed hanging in the new algorithm, this should be investigated.

Hm. Actually we knew when pushing that said test seems to never finish.
I once let it run for two hours, and it was consuming 100% of a CPU core and
didn't stop, so I'm pretty sure it's an endless loop.
I did some analysis but didn't retain the workdir (on the mistaken
assumption you already knew what's going on), so I'm recalling this from
memory:
- it's happening after the tenth (or so) call of doit (in mellin, I think,
but could be meijerint)
- the call fails, popping up through several levels as an exception, then
several more levels in the form of functions returning a None result.
Hope this will help you a bit in your own analysis.
I will submit a pull request that turns @slow into @skip.
Thanks :-)
How about attaching a @skip to the known-to-fail tests as well?
That's what XFAIL is for. Or did I misunderstand you?
