Subject: * 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.
