+   using gcc's labels-as-values extension
+   (http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html).
+
+   The traditional bytecode evaluation loop uses a "switch" statement, which
+   decent compilers will optimize as a single indirect branch instruction
+   combined with a lookup table of jump addresses. However, since the
+   indirect jump instruction is shared by all opcodes, the CPU will have a
+   hard time making the right prediction for where to jump next (actually,
+   it will be always wrong except in the uncommon case of a sequence of
+   several identical opcodes).
+
+   "Threaded code" in contrast, uses an explicit jump table and an explicit
+   indirect jump instruction at the end of each opcode. Since the jump
+   instruction is at a different address for each opcode, the CPU will make a
+   separate prediction for each of these instructions, which is equivalent to
+   predicting the second opcode of each opcode pair. These predictions have
+   a much better chance to turn out valid, especially in small bytecode loops.
+
+   A mispredicted branch on a modern CPU flushes the whole pipeline and
+   can cost several CPU cycles (depending on the pipeline depth),
+   and potentially many more instructions (depending on the pipeline width).
+   A correctly predicted branch, however, is nearly free.
+
+   At the time of this writing, the "threaded code" version is up to 15-20%
+   faster than the normal "switch" version, depending on the compiler and the
+   CPU architecture.
+
+   NOTE: care must be taken that the compiler doesn't try to "optimize" the
+   indirect jumps by sharing them between all opcodes. Such optimizations
+   can be disabled on gcc by using the -fno-gcse flag (or possibly
+   -fno-crossjumping).

+    with the bodies combined.
+
