+-- Don't use `forkProcess` in gtk2hs!
+-- Because `forkProcess` haven't any protect when spawn process, [_$_]
+-- so you will got two processes *race condition*, when those two
+-- process access same resource will crash your program.
+-- Solution is use `runProcess` or `runCommand` instead, [_$_]
+-- Because those functions add MVar to make sure two processes won't
