--- Comment #2 from Mark Millard <markmi at dsl-only.net> ---
If one is going to look into this in a amd64
context it is important to be using head -r313772
or later in order to avoid fork sometimes not
preserving the stack pointer on the child-process
side of things --at least if experimenting with
port or buildworld buildkernel builds as a means
of testing.

Getting past that stack pointer problem is what
allowed me to see this problem during build
activity, which started me down this exploration.

[My tests for aborting in sh`forkshell if fork changes
the stack pointer are still in place but there have
been no failures so far.]
