a data rate threshold tool?

[Zhang Weiwu <zhangweiwu@realss.com>]

Hello. I found my application, which was supposed to run 10 hours,
either run and starve every other service on it, or doesn't run at all.
Even with nice and ionice, I cannot avoid other web services starved by
this application. And it has to run on the production server.

One trick that comes to my mind is to use a data rate threshold tool to
limit the data rate input is fed to the application.

$ threshold --rate 20KB/s < data_source | my_greedy_application

Is there such a tool in Debian?

Thanks. Running Debian 5.
