plot() is very slow in Octave 3.0.1, but OK in Octave 2.1.73

I use mandriva.. The change between Octave 2.1.73 and 3.0.1 that 
probably is the cause of the slow up is that the 2.1.73 version of 
Octave used temporary files to talk to the gnuplot process, whereas the 
new version uses pipes.. I suspect that the posix layer that cygwin uses 
to emulate posix pipes on a windows machine is slow. This is why the 
mingw binary of Tatsuro is so much faster as it doesn't have this layer..
