Working with very large text files

Hi,
I'm working on a server which writes text to large log files. The
problem is that these files are 1 GB and when I open them with perl,
perl tries to load the entire file into the memory and fails when XP is
out of memory.

I only need to use the text written in the last 5 minutes, which
shouldn't take more then a couple of megs, but since I'm using XP, I
can't use `tail`.

What code doesn't make perl load the entire file into the memory?

.
