I seem to have stumbled upon the actual STC.  Just increase those values, 
launch two MinTTY terminals, and try to use Cygwin in the second while the GPG 
pipeline is running.  All will be well for a while, but eventually the second 
window will start to behave strangely.

I used 64k and 64M (capitalization is important to dd), and the failure I 
observed is that “man” commands wouldn’t always return you to the shell 
properly after exiting from the piped-to less process.

Some kind of memory leak, perhaps?
