I am pointing at tiny bits of the code that recently got
another possible form -- smarter at Alphas, very least ;-)

Instead of this "call pair", how about:

save_and_cli(oldflags);

I happened to notice the appearance of this when I compiled
some VGER snapshot for Alpha, and it failed linkage because
somebody used this "function" ( nee, macro ).
It was trivial to write the patch, though :-)

At an alpha the amount of assembly statements is halved,
as the entire processing happens with single PALcode call.
(Tiny things try to slow the beast down, don't burden it.)
