This probably happens because GDB is careful about job control (particularly tcsetpgrp) and gdbserver isn't. Or maybe it's because both are too careful about job control. This may be a rat's nest. If we can't get it to work, perhaps we should restrict pipe to non-native targets. -- Daniel Jacobowitz CodeSourcery
