+/* The size to align memory write packets, when practical. The protocol
+ does not guarantee any alignment, and gdb will generate short
+ writes and unaligned writes, but even as a best-effort attempt this
+ can improve bulk transfers. For instance, if a write is misaligned
+ relative to the target's data bus, the stub may need to make an extra
+ round trip fetching data from the target. This doesn't make a
+ huge difference, but it's easy to do, so we try to be helpful.
+
+ The alignment chosen is arbitrary; usually data bus width is
+ important here, not the possibly larger cache line size. */
