32fa82a56a * Acquire a global GC lock to prevent new temporary root files from
being created after the garbage collector has read the temproots
  directory.  This blocks the creation of new processes, but the
  garbage collector could periodically release the GC lock to allow
  them to run.

89c9bc11ab * Add a test for a more subtle race: a process starting after the
temporary root files have been read but creating outputs before the
  store directory has been read.

1328aa3307 * Start of concurrent garbage collection. Processes write temporary
roots to a per-process temporary file in /nix/var/nix/temproots
  while holding a write lock on that file.  The garbage collector
  acquires read locks on all those files, thus blocking further
  progress in other Nix processes, and reads the sets of temporary
  roots.

a7668411a1 * Add a test to check whether concurrent garbage collection (i.e.,
running the collector while builds are in progress) works
  correctly.  The test currently fails.
