As a example, look at gnokii. It used to run fine on NetBSD, then it
grew threading, and stopped working.
Why? So that morons could write:
if(dtr is true) break;
(I haven't tried to run it on NetBSD in three years. I suspect it has
Writing good multithreaded user-space code is really *HARDER* than
writing kernel code. If you think about this, you realize why
"professional" application code is often so crappy, huge, bloated,
Leaning to write co-routines and select/poll interfaces is takes a bit
more brain power at first than writing the above busy-loop, but is SO
MUCH easier to debug that the effort pays off.
I think that the postgresql people know this.
