For number 1) you have to understand the previous messages on this issue.
This isn't a problem with octave but with cygwin.

For 2) many memory leaks have been plugged since 2.1.42, even 2.1.50 should
have many fewer leaks.. Though I believe the very latest versions of
octave have yet fewer leaks. So the only real fix for this is to install
a newer version of otave. Unfortunately, no one has yet proposed a packaged
version for windows of the latest releases. Hopefully someone will soon..

David
