I looked back as far as Nov 1 on m-c and found that asan bc3 and bc4 were long-running even then. There is intermittent variation in the job time, but it looks like that variation had existed well prior to Nov 8: I think we just need more capacity, and I also favor more chunks.

...unfortunately based on a rev that closed m-c (bug 1317296).

Attachment: increase mochitest-bc chunks to 10 for linux64-asan only

This increases mochitest-bc test chunks for linux64-asan only, from 7 to 10. Most chunks run in 20 to 30 minutes, but bc3 on e10s still takes about 45 minutes -- should be good enough to avoid timeouts.

Is it okay to only adjust linux64-asan? That's the only platform hitting (or close to) timeouts, but I sometimes wonder if we should keep chunks the same across platforms.

while it is nice to have parity between types, I don't think that is a requirement- we won't have parity between linux and osx/win for a long time and we haven't for the last 6 months or longer.
