[TCLCORE] 8.3.2 almost finished - expect an 8.3.3

[Jeffrey H. <jef...@aj...>]

FYI,

8.3.2 has some more testing to be done, and then some backporting
of items that went into the main branch (8.4).  It should be out
by mid-August.

In working with 8.3.2, we realized that there will be a need for
and 8.3.3 to work on limitations inherent in the Windows OS and
how we manage sockets with Tcl.  Currently we can only service 64
simultaneous socket requests because that's what the Windows
select can manage per thread.  The solution will be to spin a
thread per socket instead (as lightweight as possible).  At the
same time we have to solve the problem with the memory leak in
using Windows threads when the C runtime is accessed (leading to
things like the 4K mem leak per exec call on Windows).

We already have some thoughts, but it will take some time to get
the solution right.  We want to get the 8.3.2 changes out because
it will be important for everybody to have a real distributed
version of Tcl with the corrected stacked channel code, among
other changes that will be in 8.3.2.  No release date for 8.3.3
at this time.
