[I know this is just done to illustrate how function names
in plugins can bind to tracing calls, but someone might
get confused by expecting more from "exec_tb" than it
actually does.]
This flag check costs nothing because "exec_tb" is
almost never called. The way it works right now, we
need -d nochain for "exec_tb" to actually generate
an event every time a TB executes.
IMO an eventual plugin API should let plugins decide whether
to subscribe to the execution of a particular TB, when
said TB is being translated, instead of providing
an all-or-nothing switch.
