still a work in progess, but progress has been made in the
handling of signals in libast/vmalloc and ksh

Erm... I'm getting the following test failues in the "buildin_tail.sh"
test module (attached as "builtin_tail.sh.gz".
):

-- snip --

AFAIK the issue boils-down to the following testcase which AFAIK
should print nothing:
-- snip --
$ VMALLOC_OPTIONS='abort' ~/bin/ksh -c 'builtin tail ; x=$( (printf
"4\n3\n2\n1\n") | tail +2r ) || print "fail $?" ; true'
fail 127
-- snip --

David: Erm... ping! ... did you had time to look at this issue yet ?
It blows-up some tests and Solaris system scripts in quite problematic
ways... ;-(
