The default soft limit is typically enough for process usage on most
Unixes, but OSX has a pretty low default (256), which you can run
into easily under heavy usage.
With this patch, we're going to aim for as much as 16384, if we're
allowed.
Fixes part of #188.
I don't love this approach, but those errors aren't distinguished by
ErrorKind, so we have to use libc or winapi, apparently. At least
nothing here is unsafe.
Addresses part of #188.
Also, refactor our message handling to be more like the tor_proto
reactors. The previous code had a bug where, once the stream of
events was exhausted, we wouldn't actually get any more
notifications.
There are some missing parts here (like persistence and tests)
and some incorrect parts (I am 90% sure that the "exploratory
circuit" flag is bogus). Also it is not integrated with the circuit
manager code.
The limitations with toml seemed to be reaching a head, and I wasn't
able to refactor the guardmgr code enough to actually have its state
be serializable as toml. Json's limitations are much narrower.
Previously I'd hoped to have it only apply to reproducible builds,
but the work of keeping it up-to-date and checking it for drift
seems to have been tripping us up. Let's try doing it the other way
for now, and we'll see how that goes.
