One way to potentially work around this is to allow the stack pages to be marked executable by explicit linking with an alternate crt0.o, or, more usefully, by way of an attribute on the file (e.g. a "chflags").

Send a set of patches to the various crt1's and I can add the GCC option so we can test this out.
