If the "non-closure" of mintty  is completely internal in mintty and not 
a handshake-mistake with the cygwin dll or the OS, then I agree. It 
seems to be the case, reading the link provided by Thomas Wolff.


For cyg Simple:
I am stuck with Cygwin 32 bit because of some tools, we use. A team is 
trying to get it to work with 64 bits, but that is not there yet.


For Thomas Wolff:
The link explains return code handling in mintty & ssh. A valid reason 
to update mitty.

Thank you, Andrey, cyg Simple & Thomas Wolff :-)
