[CentOS] e2fsck with millions of files

According to the release notes this bug has been fixed in version 1.40:

http://e2fsprogs.sourceforge.net/e2fsprogs-release.html#1.40
E2fsprogs 1.40 (June 29, 2007)
There was a floating point precision error which could cause e2fsck to
loop forever on really big filesystems with a large inode count.
(Addresses Debian Bug: #411838)

What are the odds of this getting included in CentOS 5.6?
