Don't know > if that's a big issue here? FWIW, I think that's mostly a twentieth-century problem. With modern toolchains and libraries there isn't likely to be much difference. I would suggest taking a negative approach: do not ship the non-thread-safe version unless you have positive evidence that it's meaningfully faster, or there's a known incompatibility in the thread-safe version. It only takes one episode of debugging an oh-you-should-have-used-the-thread-safe-version problem to wipe out any possible benefit from using a not-thread-safe-version, when you account for person-hours saved or wasted by each. To give a concrete example: there is no non-thread-safe version of glibc in Fedora. regards, tom lane -- packaging mailing list packaging@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/packaging
