jemalloc, Jason Evans’ general-purpose scalable concurrent malloc implementation, was recently updated to version 4.0.0. I have wrapped packages for Fedora, and will update rawhide in a few days. If you would like to test the packages already, have a look at http://users.linpro.no/ingvar/jemalloc/4.0.0/.
Update: Jason recently released updates through 4.0.1 to 4.0.3. Packages for 4.0.3 are pushed to rawhide. Builds for epel are available at http://users.linpro.no/ingvar/jemalloc/4.0.3/.
There are a few fedora packages that rely on jemalloc. If you have a chance to help testing, please recompile and test the package against the updated version. You can leave comments here, or send me a mail.

For those that would like to use jemalloc-4.0 on epel, I have built packages for epel 5, 6, and 7 as well. These will not be pushed to the official epel mirrors, as there are api and abi changes that make them binary incompatible with the existing packages in epel.
