Just re-ran with --log instead of --log-all and as you suggested, it didn't 
change much about nprof.  Results:

v8-lazystartprofiling-ganode.nprof.txt:Statistical profiling result from 
v8-lazystartprofiling-ganode.log, (9781 ticks, 7212 unaccounted, 0 
excluded).
v8-lazystartprofiling-patchednode.nprof.txt:Statistical profiling result 
from v8-lazystartprofiling-patchednode.log, (8799 ticks, 3398 unaccounted, 
0 excluded).
v8-standardprofiling.nprof.txt:Statistical profiling result from 
v8-standardprofiling.log, (18120 ticks, 0 unaccounted, 0 excluded).
