-Current overhead (with PERLDBf_NONAME) wrt non-debugging run (estimates):
- 8% extra call frame on DB::sub
- 7% output of subroutine data
- 70% output of timing data (on OS/2, 35% with custom dprof_times())
-(Additional 17% are spent to write the output, but they are counted
- and subtracted.)

-- Calculate overhead/count for XS calls and Perl calls separately.
