Currently when upgrading the base 'cygwin' package, the installer only warns
you midway through the installation after some files have been
removed/replaced.

If you have other cygwin processes running, you may be left in an incomplete
state where you can't or don't want to kill the other cygwin processes
leaving you stuck in the middle of install while you wait to be able to
finish or kill the existing cygwin processes. Even worse, several core
cygwin utilities are now broken (such as 'ps') due to the partial install.

I have done this inadvertently a couple of times when 'cygwin' gets thrown
in as a part of another intentioned download.

Today I was left in an even odder state since I ran 'setup.exe' from a bash
prompt -- leaving me in a catch-22 since if I kill the bash processes then I
kill setup but I can't continue until I kill the bash processes...
