RE: SCE-MI: String Parameter Values

Hi John,

> I like proposal 2) below. It keeps things simple.

I came to the same conclusion. The only complication is that in
a multi-threaded environment the string value pointer could be
invalidated by another thread at any time. In a non-preemptively
scheduled threading system the workaround is to copy the string,
but what about a preemptively scheduled threading system? In
such a system a thread switch could happen between getting the
string attribute and copying it. Are preemptively scheduled
threading systems (e.g., pthreads) outside the scope of SCE-MI?

I meant to add the phrases `whichever comes first' at the end of
this paragraph.
