Totally agree.  I am actually a heavy user of QEMU tracing system, just like
the rest of the tracing tools all over the world... :)

IMHO the difference between a tracepoint and a manual printf() is majorly the
reusablility part - if a debugging printf() is likely to be reused in the
future, then it is a good tracepoint candidate.
