[Discuss-gnuradio] Regarding lock protection when setting private variables in gnuradio blocks

[Achilleas Anastasopoulos]

My question arose from a comment that Jonathan made on one of the pull requests

in gnuradio (#293).

If we have a set function in a gr block that sets some private variable that is

used in the work function, do we need to protect it to make the whole operation thread safe?

Is this a standard practice in gnuradio blocks?

eg, why is this not used in "add_const_vXX_impl.h.t" ?

thanks
