I thought signals and threads were an iffy combination? Meaning that the main thread tends to intercept all signals? So what if you wanted 2 or 3 buffers? A shared variable can be buffer specific, whereas a signal may be non-specific. (I may have mistakenly used the word "signal" in my node above, in a generic manner, where I really meant "set a shared variable which would signal......."
I'm not really a human, but I play one on earth. Cogito ergo sum a bum
