Don't be silly now ;) Suspension of socket calls is done a bit more 
explicitly, through a socket event library. As far as I understand, that 
is in fact the general approach that NetBSD hopes to adopt as well one 
day, because explicitly suspending socket calls is actually rather easy 
(there is very little state involved) and saves the need for a stack per 
suspended call.

MINIX does not have support for kernel threads at all and is not 
designed to scale to larger numbers of CPUs, so performance-wise this is 
entirely acceptable for us. The main alternative would have been 
user-level threads (managed entirely within the service), which I 
decided against for the above reasons.
