I might be wrong on this because I do not have all the information, but I
think that one of the consequence of our choice to set minimum version to
2.6.27 is that we need to patch the glibc to avoid a threading issue on
x86_64. This problem do not seems to happen if glibc is builded for 2.6.32.
Again, I do not have all information on this. Allan might have a more informed
opinion on this issue.
