canRead, canWrite, eof don't seem to correlate with when a process is done.... If I run an external program that takes a while (like "svn co ...") how do I know when it is done?

Jason,
Here's what's supposed to happen:
Stream.canWrite is true while the process is running
Stream.canRead is true when the fifo is non-empty
Stream.eof is true when the process is done and the fifo is empty
Stream.readFile() waits until the process ends and returns all remaining output.
Getting this to work correctly on all OSs has been a challenge. Which versions of JSDB and OSX are you running?

False alarm -- Stream.eof seems to work correctly after all, I had a bad svn repository connection while using svn via jsdb's stream-exec and I just wasn't getting the results I expected.

ooh -- looks like readFile() is an even better choice, if I don't need to read process output as it is being streamed.
