Just increase those values, l= aunch two MinTTY terminals, and try to use Cygwin in the second while the G= PG pipeline is running. All will be well for a while, but eventually the s= econd window will start to behave strangely. I used 64k and 64M (capitalization is important to dd), and the failure I o= bserved is that =E2=80=9Cman=E2=80=9D commands wouldn=E2=80=99t always retu= rn you to the shell properly after exiting from the piped-to less process. Some kind of memory leak, perhaps? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
