--- Comment #4 from Ron Fischler ronfischler@gmail.com 2009-08-04 19:01:28 --- Note: A popular open-source terminal program, TeraTerm Pro, (see http://www.tucows.com/preview/195282) exhibits exactly the same explosive heap growth in wineserver. Looking at it's source, it is using readfile() with overlapped reads.
