I'm not sure what this means. Blocks are also a cross-platform solution. We shipped a working blocks runtime as part of Étoilé six months before Apple shipped theirs, and it's now been incorporated into GNUstep. I've used blocks on OS X, FreeBSD, OpenBSD, Solaris, and Linux. Apple (more recently) released their blocks runtime as part of LLVM's compiler-rt project, so you can use blocks without an Objective-C runtime, if you choose.
Blocks are a cross-platform solution, they're just not well supported by other compilers yet, but they're quite useable on a variety of platforms.
 Actually, they're not well supported by clang yet either - we allocate too many structures for __block variables.
