Erm... can we please merge all the Solaris/old-Linux fixes, Cedric's
patch to pass |shp->pwdfd| down to bulitins, dgk's signal fixes, the
MADV_HUGEPAGE patch etc. etc. and make a new alpha from that, please ?
I still have more patches queued (some for largepages/hugepages on
Solaris/Linux, some for largepage vs. sfio, some for more
|*at()|'ification etc.) but would prefer working from a new alpha
instead of piling my patches even higher.

BTW: Is Phong back from his vacation ?

Roland
