For sure we cannot add virtual functions to basic_streambuf without breaking
the ABI. Also, getline certainly isn't just fgets, takes a delim char, uses
traits, etc. Sure, anyway, in principle you can often speed-up special cases,
but also given that in ~5-7 years nobody else reported anything about the
performance of the synced getline, I don't think anything is going to happen
anytime soon, I could keep this open, but it would be futile, we have a lot of
work to do, for C++0x, in particular.
