I think we ought to just pick a number (in bytes) and not mention
pages at all.  

The last time I checked, the default page size on Linux/IA-64 was
16KB.  It's possible to recompile the kernel to use 64KB pages.  My
point is that it would be possible for someone to submit patch using
alloca() which meets your proposed guidelines (on the architecture
upon which the patch was developed), but which aren't reasonable for
generic code.
