to trigger/signal a rebuild for the transition 5.8.8 -> 5.10.0.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=...").
File::NFSLock - perl module to do NFS (or not) locking
Program based of concept of hard linking of files being atomic
across NFS. This concept was mentioned in Mail::Box::Locker (which
was originally presented in Mail::Folder::Maildir). Some routine
flow is taken from there -- particularly the idea of creating a
random local file, hard linking a common file to the local file,
and then checking the nlink status. Some ideologies were not complete
(uncache mechanism, shared locking) and some coding was even
incorrect (wrong stat index). File::NFSLock was written to be light,
generic, and fast.
