Concurrent compiles in separate working directories.  A new working directory 
is created for each request, on a tmpfs filesystem.  Checking out the git tree 
takes around 0.02s.

There is minimal locking involved: there's a single lock controlling access to 
the list of cached revisions, which is held for as short a time as necessary; 
it's not held for the duration of the build.  Everything else can run 
concurrently.
