You could put the pipelines in a separate script:

	% cat .login
	...
	background_script < /dev/null >& /dev/null
	...
	% cat background_script
	#!/bin/csh -f
	pipeline_1 &
	pipeline_2 &
	...

If your `background_script' could be written just as easily in Bourne shell
language:

	% cat background_script
	#!/bin/sh
	(
		pipeline_1 &
		pipeline_2 &
		...
	) &

...which gives control back to .login faster.
