#The issue we're trying to avoid is the (stderr)prompt arriving midway through a large stdout chunk
#REVIEW - this basic attempt to get stderr/stdout to cooperate is experimental and unlikely to achieve the desired effect
#note that our 'flush stdout' tcl call does not wait if stdout is non-blocking
#todo - investigate if the overhead is reasonable for a special channel that accepts stdout and stderr records with a reader to send to console in chunk-sizes we know will be emitted correctly
# - reader of such channel could be ok to be blocking (on read? on write to real channels?)... except everything still needs to be interruptable by things like signals?
#? - we want ordinary puts to stderr to be prioritized? to arrive on-screen - just not at arbitrary locations within stdout, and still must be correctly ordered wrt all other stderr
# - in our repl and code threads we don't want to put stderr/stdout writes in blocking mode and have code waiting on it
