I guess it works with PDBG in contrast to printf because PDBG (as well
as PINF, PLOG, and PERR) are macros that add a line-break to the end of
an input string, which in turn causes the string to be send to the
LOG-session server immediately. However, the backend of these macros is
the Genode::printf function that leaves things like line-breaks and
coloring sequences in the hand of the user.
