[PATCHv5 12/17] gitweb/lib - No need for File::Temp when locking

[Jakub Narebski <jnareb@gmail.com>]

When using locking to ensure that only one process is generating data
and updating cache, there is no need to use File::Temp for temporary
file.  This should improve performance.

This patch was not present in previous v4 version of this series.  It
brings this solution closer to the one in J.H. patch, because with
locking it does not use File::Temp; the locking is safety enough by
itself.
