With Android, it's *mostly* Linux (at the kernel level) except we have a whole slew of different runtime libraries that differ.  So, for much of the behavior, it will be like Linux/POSIX, but with certain libc calls and whatnot that just don't exist.  Ideally we minimize how much we differ and only when needed.

Tong, can you take a look at that?  If we need a Linux-derived Android variant of these classes, this might be a good time to look at those.  Thanks.

In general you don't.  The Android zygote takes care of launching for userland, and debuggers usually run attach-only.

That's just a half-truth, though.  We do have low-level, internal capabilities for launching,  but since that is not a supported path for developers, they are not exposed in a way we can access with POSIX-like calls.  The launch code might end up only showing up in an AOSP environment but, in any event, the attach path is the crucial one for Android right now.
