:I hate your threads. Still trying to see some parts of the bigger
:picture. But it was a reasonable design decision, I'll grant.
heh heh. Be happy, it's second generation -- the first generation
was what I did in BestWWWD which was nearly impossible to follow.
The procedure-state-based model that dreaderd uses is actually reasonably
close to what you would have to use in a threading model anyway, the
only difference being that the subroutines would not have to do
non-blocking-returns-to-the-main-select-loop.
Remember, I did this before we had a working RFMEM rfork() *OR* a
reliable aio subsystem. These days I would simply use the linux threads
library under FreeBSD (at least until we get our new threads library
working) and take the 'thousands of processes' hit (which is ok by me
since the page table is shared).
