[CentOS] /var/log/lastlog on x86_64

this problem is already known and I'm sorry to bother if an acceptable
workaround was already debated on the list.
I was getting trouble with a 'grep something /var/log*' which caused the
"Memory exhausted" message. With some deeper search I found the lastlog
file in /var/log/ to be 1.2T sized. This seems to come from the
nfsnobody's uid to be 4294967294 on x86_64 system (and -1 on i386) and
the pre-allocation space for every uid (so from 0 to
...4294967294...hum..) from lastlog.
Since I do not use NFS at all, can I just erase the nfsnobody from
/etc/passwd and start with a blank lastlog file (this looks like a great
way to nuke my system)? Or do I need to explicitly exclude this file
from all my search? How do you -x86_64 users- deal with this? It seems
the mainstream people don't see this as an issue.
