`sclang` uses 80% CPU

[giuliomoro]

Just start it with a patch like this (i.e.: doing nothing) and - once scsynth has booted, you will get CPU usage around 80% for sclang. It should not affect much the performance of the audio (as that runs at a higher priority), but it may affect, e.g.: the networking/OSC stuff?

• note that the CPU usage reported by top is as percentage where 100% corresponds to whatever has been left over from Xenomai (for instance if your audio is using 25% CPU, as reported by cat /proc/xenomai/stat, then 100% reported by top will actually be 75%).

Looks like the same issue as https://github.com/supercollider/supercollider/issues/2144 . We'd really like to fix that but don't have a lot of people to look it over at the moment
