was already cleaned up with the OpenBSD port, this doesn't require massive changes. Since current NetBSD is ELF-based by default, we don't make use of the ELF feature, or in other words: The presence of the NetBSD feature implies ELF, since there is no support for non-ELF NetBSD. The page-protection feature of the generational GC had to be turned off, because currently NetBSD 1.5.2 doesn't provide access to the faulting memory address in SIGSEGV signal-handlers on the x86 platform. The memory is validated/mmapped in 64MB chunks in os-validate, in order to circumvent a restriction on NetBSD, that prevented me from mmapping 128MB or more apiece. It has been pointed out to me that this may be caused by the default ulimit on data segment sizes, which seems kind of strange, but might be true. In any case the current approach works OK, and doesn't require root interaction, so is probably the better approach.
