+ Relocate bodies of DTrace probes to the statically-linked
+ VM.</p>
+ <p>
+ Due to various operating systems (in both the DTrace and
+ SystemTap worlds) not fully supporting DTrace probes (or
+ SystemTap-compatibility mode probes) in shared libraries,
+ we relocate those probes to the statically-linked virtual
+ machine. This could be seen as pollution of the pristine
+ VM by a (yet) experimental feature. However:</p>
+ <p>
+ 1. This code can be eliminated completely by the C
+ preprocessor. 2. Leaving the probes in the dyntrace NIF
+ shared library simply does not work correctly on too many
+ platforms. *Many* thanks to Macneil Shonle at Basho for
+ assisting when my RSI-injured fingers gave out. (note:
+ Solaris 10 and FreeBSD 9.0-RELEASE can take a long time
+ to compile)</p>
