Remove nextTick check for groups.

Removing this line would be nice. :)

This would cause issues when no group() has been called, but it would allow groups to be setup later (in callbacks), which would be pretty cool.

Or, perhaps, for backward compatibility, allow someone to pass options to the this.group() function. Such as this.group({"defer": true}) would disable the process.nextTick check, which is only useful if the group is going to be empty anyway.

I'm not really sure. :) This issue is over a year old. I'm going to close this issue.
