So what? If we use poll() already in daemon, upload-archive and upload-pack, and no MacOSX 10.2.8 user has spoken up with a proposal for replacement, then yet another use won't raise a complaint, either.

And if it were a problem for msysGit, I wouldn't have suggested it ;) The particular use in pager.c would be inside #ifndef __MINGW32__ #endif anyway.
