Found the program.  Under RELENG_4, its quite happy doing

cryptotest -t 4 -p -a aes 100000
92.781 sec,  200000    aes crypts,      16 bytes,    34490 
byte/sec,     0.3 Mb/sec
dispatch->invoke: avg   3599 ns : min   1955 ns : max   55315 ns [800048 samps]
     invoke->done: avg  56574 ns : min  32406 ns : max  158121 ns [800048 
samps]
         done->cb: avg   3707 ns : min   1677 ns : max   57270 ns [800048 
samps]
        cb->finis: avg   5286 ns : min   2235 ns : max   63695 ns [800048 
samps]

... continuously.  But I am pretty sure this is an IRQ routing issue and 
not a HiFn specific thing.
