+ * Set up a sequence of staggered jumps, forwards and backwards with

+ * JITed native jumps. On some architectures, for example MIPS, a large
+ * PC-relative jump offset may overflow the immediate field of the native
+ * conditional branch instruction, triggering a conversion to use an
+ * absolute jump instead. Since this changes the jump offsets, another
+ * offset computation pass is necessary, and that may in turn trigger
+ * another branch conversion. This jump sequence is particularly nasty
+ * in that regard.
+ *
+ * The sequence generation is parameterized by size and jump type.
