the PMT library is really sucking face with 23% of the time, surpassing
libm, libc and libstdc++ which are at 22%.
I can certainly think of ways of reducing the PMT usage... there are
numerous cases where I will parse a PMT list, and pass the list to
another method only to re-parse it because it is convenient rather than
passing tons of parameters. :)

and just to clarify, i'm not saying it would be extremely beneficial to
optimize the PMT use through all of the inband code... but most
certainly in the TX and RX chain through the inband code. Optimizing
the parsing of TX and RX messages would seem key.
