There is a (cygwin-imposed) 128 meg limit on the largest chunk of
memory that can be allocated. This can potentially effect everything,
but may be noticed most with unu and vprobe.
Windows
Don't try to use piping ("|") to connect invocations on unu. Piping doesn't work
correctly on Windows, and I don't think its my fault. It works
perfectly everywhere else, including cygwin.
