But surely, for the operations that matter to Ruby (say "read" and
"write"), the overhead of *calling* C's IO library must be - what -
1E-9 seconds?

If the libraries are fast enough for every other C program, why are
they not fast enough for Perl - just another C program?

Or is it more than just "read" and "write" that's at stake here?
