Ok, I'm definitely -1 on adding this then. First of all, you're only
adding this for Unix systems, but working on adding a facility that is
generally useful. This is exactly the sort of usage I'm against.
A better approach would be to define an ooRexx thread object that
provides different facilities, including the ability to have named
values associated with the thread. This is something that could
easily be returned by the .Context object.
