Is this going to change for the next major release? There's an awful lot

If you mean for 1.9.x then there is no way to predict that.
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.
It's possible that the next major release will introduce cygwin2.dll. That
would be a long time coming.
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?
Given all of the features that Corinna
added I think it's likely that 1.7.x is bigger and potentially slower to
load.
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?
