I tested with 2.5.1, with the latest snapshot and with the latest from
git master, on 32 and 64 bit. In all cases, the above results in about
1000 'select_stuff::cleanup: calling cleanup routines' lines in vi.out,
give or take, depending on my typing speed.

Yeah, no worries.
Again, I can *not* reproduce this. Maybe we should start at the basics,
a cygcheck output. What's your OS? I'm testing on a 64 bit W10.
What's your terminal? I tried from Mintty as well as from a console.
