Lout memory consumption

[Jeff Kingston]

I've been doing some measurements of Lout's memory consumption,
to see if there are any leaks or any savings I can make.  The
results when running the User's Guide are shown below.  It seems
that memory usage excluding the Lout binary and stack space is
totally dominated by object memory, which is where the definitions
and currently-being-buit pages are stored.  The output shows that
immediately after definitions have been read, memory consumption
is 2763562 bytes, having reached a maximum of 2774004 bytes some
time earlier.  At end of run the total memory consumption is
8091922 having reached a grand maximum of 8102164 bytes at some
point during the run.

Although this output does not show the breakdown of object memory
between the free list and in use, I have done other checks which
prove that object memory is not leaking.  Conclusion: Lout is a
memory hog, and there is nothing quick that I can do to improve
the situation.  Jeff.
