wow, a tonne of code gone, nice

[ralphtheninja]

@filoozom Btw recruitment time, would you like to be invited to the level org? 😄

[filoozom]

@ralphtheninja Well, I might be working a tiny bit on upgrading the RocksDB dependency a bit, but probably won't have a ton of time to be very active. I guess it all depends on what you expect from your members. 😄

I also worked on a new Travis configuration file to prebuild musl versions of this library in addition to the glibc ones, and started working on ARM builds but I can't get them to cross build.

Is there something left to do on this PR to get it merged?

That's totally fine. Most members aren't that active, so no pressure at all.

[filoozom]

Well, count me in then!

@filoozom We could use the help in updating snappy for leveldown as well.

@vweevers Patch or minor? I vote minor, just changed my mind to patch 😉

[filoozom]

It's basically a bug fix for musl to be honest. Nothing changed, no feature added, no speed changes, a patch should be just fine. It was even a patch for snappy.

[vweevers]

Does snappy follow semver?

[vweevers]

I vote minor, just changed my mind to patch 😉

Patch it is! I defer to your judgement on this :)
