NSS consistently fails to build on MIPS because it hits the 20 hour timeout specified in 'package->alist' in build-aux/hydra/gnu-system.scm.
As a one-time hack, I modified the database on Hydra to increase the timeout for <http://hydra.gnu.org/build/442531> to 40 hours, and found that the build succeeded after about 28.25 hours. The overwhelming majority of that time is spent in the test suite -- the build phase takes only about 10 minutes on MIPS -- but I'm reluctant to disable the test suite for a library as security-critical as NSS. So, we either need a way to set the timeout on a per-package basis, or we need to increase the default timeout in gnu-system.scm. I still don't know how much to increase it, because in this case there were no other builds happening on the machine for much of the time, whereas typically there will be two builds assigned to each MIPS build slave. Suggestions? Mark
