More observations:

* This also happens on a Windows 8.1 VDI install with a different 
AV/security solution-- different enough from my machine that I don't 
think the Windows/app environment is the cause of this, it looks more 
strongly like a Cygwin issue to me.

* 
<http://pubs.opengroup.org/onlinepubs/9699919799/functions/pselect.html> 
clearly states that select() must zero out all FD_SET bits when it 
returns 0.

* Moving the mouse cursor around over the console window (at a bash 
prompt, without mouse modes enabled) makes this issue happen *much* more 
frequently.

I'd investigate further but on current Git sources, 'make' fails for me 
with this:

/home/cgull/src/newlib-cygwin/newlib/libc/configure: line 2164: syntax 
error near unexpected token `..'
/home/cgull/src/newlib-cygwin/newlib/libc/configure: line 2164: 
`NEWLIB_CONFIGURE(..)'
