Can I spawn a subprocess in such a way, that its stderr is redirected to parent proc's stderr, whereas stdout can be read normally?
Alternatively: after I run startProcess, can I somehow detect which of outputStream vs. errorStream has some pending data I can read? Or, are there non-blocking versions of read on outputStream & errorStream? I need to distinguish between stdout vs. stderr, so poStdOutToStdErr is a no-go. Also, I need to support all major desktop platforms (Win, Lin, Mac); if you know a solution for only one of them, I'm still interested - there's still hope somebody may chime-in with a solution for the others later...
