------------------------------> Notes start <------------------------------ If you use GtkSocket/GtkPlug with multi-processes framework. DON'T use function `forkProcess` to spawn process! Because `forkProcess` just simple call C `fork`, haven't any protection, then two processes will got *race condition*, you will get X Window error (such as `BadWindow`) when those two processes try to access same X resource. So use `runProcess` or `runCommand` instead. Above two functions add MVar lock when spawn processes (call c_runInteractiveProcess) to make sure two processes won't get *race condition* problem on X resource. ------------------------------> Notes end <------------------------------ > > I can't use the latest release of gtk2hs because it doesn't work with GHC > 6.12.x. So if anyone has > any advice, please let me know! Axel has working on cabalized version, i think he will release it very soon.
