On Ubuntu/Unix, you can use ulimit to restrict how much memory is
available to processes started under a particular shell.  This will
not necessarily give precisely the same behaviour as a hardware limit
(since that will also affect kernel memory usage) but it it's easy to
vary.

For example

  $ ulimit -v 512000
  $ bzr commit ...
