people are starting to bump into the limit of 50 dns workers.
...
raise it to 100 for now. we need a better solution long-term.
but alas, there are no better solutions that are also portable.
hm.

Fix a symptom for a bug that straycat found.
...
Apparently in rare cases poll() is returning POLLIN for an idle
dns worker. It reads no bytes, presumably because the idle dns
worker didn't write anything in the first place. Gosh, who knows.
Now we only trigger the assert if the idle dns worker actually
tries to send an answer to us.
