In a general sense, yes, GNU Radio is well suited for real-time signal 
processing of data streams.  That said: "Real time" is only meaningful knowing 
the performance criteria.  What sort of performance do you require processing 
for?

IIRC (Tom? Eric?): GNU Radio uses the standard C++ "new" command for most 
memory allocations -- and thus it is memory from the heap.  One can always 
overload this method globally or locally if required, to provide memory from 
pools or other means.

Yes.  Your choices are a single thread for all or 1 thread per block. - MLD
