[PATCH] mlqueue scheduler tracing

- Reply-to: thomas dot koeller at baslerweb dot com
Hi,
when using the ecos tracing facilities with buffered output I found
that the multi-level scheduler (mlqueue.cxx) generates a line of
output for every time slice consumed by a thread, so my tracing
buffer was filled up with countless lines telling me that the scheduler
had decided to re-schedule the current thread, something I wasn't
interested in at all. The information I was collecting had almost
been shifted out of the buffer. Looking at mlqueue.cxx I found
that obviously someone wanted to make real sure that nobody
could ever turn off these messages without editing the code, so I
did just that. Patch attached.
Thomas
