Currently a strange error with the nightly build:

Compiling nix-test v0.0.1 (file:///Users/travis/build/carllerche/nix-rust)
Build failed, waiting for other jobs to finish...
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

it says "this is a bug."
strange. maybe temporary

Has anybody seen similar errors? I cannot reproduce this. Sometimes it builds, sometimes the compiler seems to crash but it doesn't seem to be related to the mq code.

There have been some intermittent failures. I haven't done much work trying to track them down. I will try to look into it a bit tonight.

It looks like both rand and rust-nightly are slightly out of data. Maybe this is fixed with the latest versions.
On the other hand it says that it's a compiler bug. No activity on the ticket I opened so far.

I'm trying a rebuild.

Looks like the build passes now.

Thanks! Merged: bd265fd

Thanks for merging. Will be adding the missing functions soon.
