LTFViewr5u is the best solution:

This program was designed for viewing large (>1GB) text files.
It uses little memory and is able to open a gigabyte file instantly.
Background file indexing makes browsing even faster.
It allows the user to perform high-speed complex text search by means of plain 
text or regular expression.
No installation is needed.
The executable is only 572KB!

FWIK, Ultra Edit supports edit large files, it won't load the whole file into memory but load some and edit some. But it's not free.

I guess there are many editors which based on mmap() will do the work.

Not mmap() but file mapping. msdn.microsoft.com/en-us/library/aa366556%28VS.85%29.aspx –  Ignacio Vazquez-Abrams Dec 3 '10 at 5:46

gvim should work OK
