FIXME re: "dynamic linking delayed" to runtime.

The existing text of the Guide hints at this point but doesn't discuss
it directly.  This FIXME is merely a reminder note to investigate this
issue in further detail and perhaps add text here on the question.

+% FIXME-SOON:
+
+%   A commonly asked question is whether or not separated distribution (i.e.,
+%   dynamic loading of a module that is expected to be present on the
+%   downstream sytem) triggers the copyleft requirement.  The text above
+%   hints at that issue, with reference to Java runtime.  However, here would
+%   likely be the natural place to discuss that issue in more depth.  I have
+%   never actually studied this specific question in a GPLv2 vs. GPLv3
+%   analysis, and as such I'd want to do that first.  Furthermore, the FSF
+%   has not publicly opined on this question to my knowledge, so I'd want to
+%   see possible update to
+%   http://www.gnu.org/licenses/gpl-faq.html#GPLStaticVsDynamic to mention
+%   this issue before opining about it in the Guide.
+
+%   I'm not aware, BTW, of any dissenting opinions or disagreements among
+%   copyleft advocates on this point.  I think it's just a question that is
+%   rarely opined on but often asked, so it's fitting for this Guide to cover
+%   it, and for addition on this point in the FAQ.
