Summary: MemoryBuffer copies input file for page sized files
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Core LLVM classes

This is bad, such files aren't *that* unlikely, and mmap is a big performance
win. I think in most situations we can just mmap an extra page, but need to
verify/test.
