I can understand why you can’t spawn processes (it prevents fork-bombs and similar attacks) but what damage can be caused by a bundled dylib? Sure, you can change your build process to make the dylib static, but I’ve had trouble with complex 3rd party code [i.e. the Erlang interpreter/runtime] that has a heavy dependency on dynamic library loading.

I can only speculate, but: If you can call out to a dynamic library, wouldn't that make it possible to download a library and execute unapproved code? Apple's not happy with downloadable executables other than JavaScript in the WebKit sandbox.

I don't know enough about HFS+ and dyld on iOS to know if it's possible to stop that.
