bmeck/node-fork — comment on commit e174563154020b569667b7e026c1401eabf04389
File: lib/fork.js line 51
By indexzero:

1) You can't set `NODE_CHANNEL_FD` because it is a reserved environment variable used by core. Thus we have changed it to `FORK_CHANNEL_FD`.

2) You need `FORK_SHIM` when you are forcibly telling a `0.6.x` process that it should not use the native `child_process.fork`. I know that seems a little strange, but we need this functionality. Inside a `0.4.x` process it has no meaning because `child_process.fork` is not defined.
