Fix the following valgrind warning:
Conditional jump or move depends on uninitialised value(s)
at 0x7D64E7: v8::internal::GlobalHandles::IterateAllRootsWithClassIds(v8::internal::ObjectVisitor*) (global-handles.cc:613)
by 0x94DCDC: v8::internal::NativeObjectsExplorer::FillRetainedObjects() (profile-generator.cc:2849)
# etc.
This was fixed upstream in r12903 and released in 3.15.2 but that commit
was never back-ported to the 3.14 branch that node.js v0.10 uses.
The code itself works okay; this commit simply shuffles the clauses in
an `if` statement to check that the node is in use before checking its
class id (which is uninitialized if the node is not in use.)
Evented I/O for V8 javascript.

export PYTHON=/path/to/python
$PYTHON ./configure
make
make install
Windows:
vcbuild.bat
You can download pre-built binaries for various operating systems from http://nodejs.org/download/. The Windows and OS X installers will prompt you for the location to install to. The tarballs are self-contained; you can extract them to a local directory with:
tar xzf /path/to/node-<version>-<platform>-<arch>.tar.gz
Or system-wide with:
cd /usr/local && tar --strip-components 1 -xzf \
/path/to/node-<version>-<platform>-<arch>.tar.gz
To run the tests:
Unix/Macintosh:
make test
Windows:
vcbuild.bat test
To build the documentation:
make doc
