Hi Miklos,

indeed this is another problem which we've also discussed during the planning 
for the cfg framework migration work, its present for example in the ratelimit 
and carrierroute modules. 

Quite a few kamailio modules implemented also their own version of reload 
functionality with a FIFO command, e.g. "reload_fifo" in 
modules/carrierroute/cr_fifo.c. This is more or less a similar use case like 
the cfg framework represents (atomic reload of a variable), but with a a bit 
more complicated data structure (route_data_t).

So having a generic version for this in the cfg framework would be indeed nice 
in my opinion.

Cheers,

Henning
