FWIW, I don't recall any reason why it shouldn't work with unexec,
either. To the best of my recollection, unexec was generally broken at
the time I wrote the patch; I fixed unexec and then it worked without
purespace, but the unexec fixes never made it into master until Eli
re-did them a while later.

(IIRC, this patch predates the nativecomp merge and that affected pure
space a little, so that probably needs to be kept in mind.)
