The extern-mod patch finally landed! The last bug: it turns out that something on Mac OS X wasn't right in our run code (that shells out to create a new process), and if you supplied environment variables, it was extending the environment and not overwriting it. On Linux, the code was correct, which meant shell commands failed because among other things, the PATH was getting set to "". I changed my test code that was calling the run code to explicitly fetch and extend the existing environment, and that was the last fix.
The next big thing to finish will be using workcache. I'm realizing that the workcache library itself needs some work before rustpkg can use it. The first thing to do was to change it so that it actually saves and reloads its database to disk, so that you can see changes in between runs of rustpkg, and not just within the same run. I did that, and now it's complaining about something missing from the file when it reads it back in, which is at least progress.
When running up-to-date master on my local machine, I was noticing a segfault while building the docs that obviously didn't happen on the bots, but it seems to be due to the new scheduler and the handling of stack overflows (I git-bisected and saw that the first bad commit was the "Turn on the new runtime" commit). There's a patch in the queue to increase the stack size, so I'm going to go home and hope it'll magically be fixed in the morning.
