The difference here is 0.0034 seconds. This sounds tiny but this sum-up

OS/Net with today's rules).
Whenever facing an optimization issue like this, the questions needs
to be asked:
* Can I avoid needing to do a slow thing at all?
* Can I make a slow thing faster?
* Can I defer using the slow thing to only when it is needed?
It seems that in this case there are a bunch of libraries supporting
internationalization which do not need to be loaded in order to
perform the function 'mkfifo'. Defering loading these libraries until
point of use may cause them to usually not be loaded at all, and
therefore there is considerable performance boost.
