Piping can be a gotcha on NT, though it seems to have more issues with file associations.

Running things under strict and -w make me wonder about the lines:

my $read="READ$name";
my $write="WRITE$name";
pipe($read,$write);

You're using symbolic references here, as pipe expects filehandles to connect together. Create the handles explicitly (with the open command) and try it. You might also enable warnings as I did, to see if the parser gives you better errors. (I think you need to create FileHandle objects for $read and $write.)
