# Once replacing system JACK libraries is possible, it's likely that
# jack-client IUSE will need blocking to avoid users accidentally
# configuring their systems to send PW sink output to the emulated
# JACK's sink - doing so is likely to yield no audio, cause a CPU
# cycles consuming loop (and may even cause GUI crashes)!
