^ Multiplexed I/O
190689 [vladgalu gma] I'd like to use Ruby for a quite high performance networking tool.

|   190750 [agorilla gma] (`cdir.rb`) was unexpected at this time.
|   190752 [ljz asfast.c] Hmm ... I wonder if this needs to run in a .cmd file instead of a .bat
|   190756 [agorilla gma] Same results.   Deleted the .bat file, and called it explicitly

    |     + 191634 [halostatue g] I'm going to start from a few basic principles, because Ruby worksdifferently than you think it does, and that's kinda obvious from howyou're not getting this.
