...

Is there any penalty/drawback if multithreading gets supported by default and without any extra option?

Not according to the release notes: ''Existing (or new sequential) applications can be built and run without code changes, on either a sequential and a multi-threading capable installation of Geant4 - provided, of course, that mandatory changes are made to address other migration issues.''

However, since ''the default build of Geant4 is sequential'', I think it would be best to do the same for the port for now and only enable the multi-threading if required by users. -- Ticket URL: <https://trac.macports.org/ticket/43593#comment:5> MacPorts <http://www.macports.org/> Ports system for OS X

Indeed the keyword `+threads` seems to be the winner, but it also looks like some ports might need some clean up to get rid of those `no_*` variants. -- Ticket URL: <https://trac.macports.org/ticket/43593#comment:7> MacPorts <http://www.macports.org/> Ports system for OS X
