* 1000th revision! * A test to verify that locking of output paths (caused by concurrent invocations of Nix) works correctly.

* Make sure that no build hook is set by default in the tests. * Don't use `seq' - some primitive, obsolete operating systems (Darwin) don't have it.

* True parallel builds. Nix can now run as many build jobs in parallel as possible (similar to GNU Make's `-j' switch). This is useful on SMP systems, but it is especially useful for doing builds on multiple machines. The idea is that a large derivation is initiated on one master machine, which then distributes sub-derivations to any number of slave machines. This should not happen synchronously or in lock-step, so the master must be capable of dealing with multiple parallel build jobs. We now have the infrastructure to support this. TODO: substitutes are currently broken.
