Hello people from D-land.
To summarise my problem: I have a program in the terminal (Posix)
with two threads: one which my main program is run on, and a
second one which polls input via `poll(...)` and `read(...)`.
Let's call main thread T1, and a semi-blocking input-thread T2.
Every second T2 checks if T1 is terminated by checking if the a
global flag is set to true. This is done with a
`while(global_flag)`.
This feels to me like iffy code. So my question becomes: what is
the best way to do this check with?
Also: I do not know that much about multithreading. __gshared is
super global in my mind, but unsafe. Also bumped into the word
mutex, but I also do not know what it means.
// i have tried Thread.isDaemon(true), but never managed to get
the thread to terminate. now i use `spawn(...)` and don't see a
clear way to use that. is it worth looking into even more?
