now, depending on how large the file is, slurping it may be faster than

Slurping is fun, but only works if you can fit the file in memory. The
moment you run into a too-large file, that approach fails hard.
On the other hand, I've gotten excellent performance out of while()
{sysread(); process();} on multi-GB files, so I'm definitely with you on
the slowdown in <FH> calls.
