/* Temporary facility for exploring problems with Pioneer DVR-216D which
does not end writing of DVD-R.
This code does not hamper normal operations but causes some extra
messages to stderr and lots of text lines in File

/* This solves a problem with Pioneer DVR-216D.
Writing of sequential DVD-R[W] happens unnaturally fast and leaves no
impact on the media. The drive stalls at the end of the burn run. Only a
power cycle makes it usable again.
Move the next line outside this remark and remove all blanks up to "define".
# define Libburn_pioneer_dvr_216d_tesT 1
Apparent reason:
One may not read the buffer capacity more than once before it is full
and physical burning begun. Strangely this happens only with libburn and
cdrecord-2.01.01a64 -v which both write DVD-R in 32 KB chunks. With
wodim's 62 KB chunks there is no endless drive business.

Needed is a more intelligent management of probing.
Note to myself: check whether feature interpretation can replace probing
