Only if you need immediate code upgrading in _this_ loop,
which seems unlikely.
Typically there should be a semi-infinite top-level message
receive/send loop, which calls into short-lived lower-level
worker loops, like your binary parsing thing. Only the top-level
loop should have to care about code upgrades.
