A computer is a state machine. Threads are for people who can't program
state machines.

What do folks think about event-driven programming as
a substitute for threads in UI and process control settings?
I wrote the service processor code for the Sicortex Machines using libevent.a and I
thought it was very lightweight and fairly easy to think about. (This was a thing running
on ucLinux on a tiny 16 MB coldfire that managed the consoles and power supplies and temp
sensors and JTAG access and booting and so forth.)
Tk (IIRC) has a straightforward event driven model for UI interactions.
Meanwhile, the dropbox plugin for my Mac has 120 threads running. WTF?
This was triggered by the fork/spawn discussion.
