Maybe there is a need for a lowest common denominator only version of Pipe or Wheel::Run? One that only uses Socket::INET perhaps? Heck, develop it on Windows so that we know we're dealing with the LCD. That way, it can be portable, consistent, and stable, although possibly a lot slower. Once that is stable, we can write separate modules that overload the base class for performance, if requested. That reminds me, isn't some of this kind of thing being done in the core of POE anyways? There's a perl version, but for raw speed there's an XS version? use POE qw( POE::Pipe ); new POE::Pipe::TwoWay( optimize => 1 ); In most cases, I would much prefer a stable & consistent implementation over a fast one. I'll take a poke at it sometime after LinuxWorld (if nobody else does) when my schedule starts to be less hectic. I'm thinking more about the Win32 port because I'm being asked to port a POE app to windows that uses Wheel::Run and Pipe quite extensively. I haven't even started to look at this - mostly because it seems scary considering the notes at the end of the Wheel::Run manpage. -Al Tobey ******************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
