The previous patch (namespace: enable per namespace alarm/signal)
implemented per elf namespace signals for common usecase of alarms.
But, as Nadav explained, it failed to allow application in a separate
ELF namespace to install its own handler for signals related to a
page fault, division by zero

Before patch, netperf netserver.so and netperf.so could not be run in
the same VM. The netserver reports "error starting alarm timer,
ret 3 errno 28".
The patch make alarm (and also signals) per namespace specific, in the
wat as environ was made per namespace specific in
e93
The first patch is unmodified from what I aready sent to mail list a while ago.
The second patch fixes problem Nadav noticed (and suggested a fix too) -
that "it will not really work in places where unduplicated OSv code calls
kill() or related functions". See
