Hmz, so contrary to what I thought it seems it's not only a problem on
Windows. Is is as severe on *nix as on Windows? My export (w/ fast
server over a LAN) was twice as fast when redirecting notifications to
a file. Can somebody get some numbers on some unixy platform?

But more to the point: anybody have a solution in mind? If it's not
Windows-only then some Windows defines wont help of course. Buffering
the output may be the only way to eliminate this bottleneck? What are
the pros and cons, and how hard would that be? Any other ideas?
