This is something I've suspected for a while, but finally verified.
The *(int*)0x1934=(int)taskHook thing we use to hook task start on DryOS is not a task create hook. It's more like a context switch hook, I think. Trying to debug the startup file crash, I logged the first 128 task names called with this function.
As you can see, many appear multiple times. It might be a good idea to not do strcmp() on all the task names every time.
Also, assuming this is a context switch hook, there may be other interesting ways to abuse it.
