* Added syntactic sugar to the construction of attribute sets to
...
`inherit' variables from the surrounding lexical scope.
E.g.,
{stdenv, libfoo}: derivation {
builder = ./bla;
inherit stdenv libfoo;
xyzzy = 1;
}
is equivalent to
{stdenv, libfoo}: derivation {
builder = ./bla;
stdenv = stdenv;
libfoo = libfoo;
xyzzy = 1;
}
Note that for mutually recursive attribute set definitions (`rec
{...}'), this also works, that is, `rec {inherit x;}' is equivalent
to `let {fresh = x; body = rec {x = fresh;};}', *not*
`rec {x = x}'.

* Catch SIGINT to terminate cleanly when the user tries to interrupt
...
Nix. This is to prevent Berkeley DB from becoming wedged.
Unfortunately it is not possible to throw C++ exceptions from a
signal handler. In fact, you can't do much of anything except
change variables of type `volatile sig_atomic_t'. So we set an
interrupt flag in the signal handler and check it at various
strategic locations in the code (by calling checkInterrupt()).
Since this is unlikely to cover all cases (e.g., (semi-)infinite
loops), sometimes SIGTERM may now be required to kill Nix.
