If you get messages like this:

  cannot start worker (writing to file: Broken pipe)

or

  error: unable to fork: Cannot allocate memory

then you could try the following workaround:

  echo 1 > /proc/sys/vm/overcommit_memory

The underlying problem is that Nix allocates a large amount of virtual memory
address space, which can trigger the overcommit limits at unpredictable moments
(such as when forking).
