I was just asking about intentions. Do the core developers *want* to
pile up new features and breakages over a period of many years and
release them in a huge batch, or do you prefer to release smaller
batches more often?
My preference is clearly written between the lines, but I only want to
know what your preference is, not change it.

Do you have a sense for what would make the next major release
cygwin2.dll and not cygwin1.dll? Obviously an API or ABI breakage would
require a new DLL name, but do you have something on the wish list that
would require that, which was put off this time around?

Yes, the v1.7 cygwin1.dll I just downloaded is about 28% larger than the
current v1.5 DLL. This doesn't worry me. 0.7 MB is about 4 cents worth
of RAM and disk space. (Yes, I checked. I'm such a geek.) Load time
is irrelevant to me, because I run cron; the DLL stays loaded all the
time. I guess the larger size could make it overflow CPU caches more
often, but the L3 cache on Intel's newest desktop CPU is about 3.5x
larger than the v1.7 cygwin1.dll.
What I was really asking is about execution time. Does it run faster
with all those if (win9x()) { ... } else { ... } logic forks removed?
Or conversely, perhaps there's new completeness or correctness code that
slows some things down?
