[OSM-talk] Osmosis error with multiple bouding boxes

[Brett Henderson]

The pipe connection documentation is a little vague.  It doesn't quite 
work that way.  Once a task reads a pipe, the pipe is consumed, multiple 
tasks can't read the same pipe.

What you need is a new "tee" task that will allow you to send data to 
two destination tasks.  Won't take much effort to write, just hasn't 
been needed yet :-)  I'll try to knock it up over the next few hours.
