Why do OS not support erlang's lightweight process?
Tue Aug 29 05:21:56 CEST 2006
Another possibility is OSE by Enea (http://www.enea.com/templates/Extension____258.aspx). The Ericsson guys may have more to say about it . I only heard it in passing and never used it.
 Rumour being it originated from Ericsson. To be taken with large grain of salt. Definately Ericsson is listed as an early adopter (1988).
