It does the samples statistically, and does not always get the numbers
right, also, it may be an effective 99%+, which rounds to 100%. DPMI_INT
is a function that handles all real mode calls, including file - I/O.
Still, it would perhaps be useful to be able to tell gprof to ignore
this fxn, since it is only useful if file I/O is the actual bottleneck.
