Creating symlinks (/data/local/tmp/*) doesn't seem to work
on android-L (tested on nexus5). I cannot find any official
documentation yet but just guess it's a measure for security
attacks using symlinks.
The tests failed with 'permission denied' errors.

os/signal depends on a few unexported runtime functions. This removes the
assembly stubs it used to get access to these in favour of using
//go:linkname in runtime to make the functions accessible to os/signal.
This is motivated by ppc64le shared libraries, where you cannot BR to a symbol
defined in a shared library (only BL), but it seems like an improvment anyway.

The man page for sigaction(2) on OS X doesn't guarantee that SA_RESTART
will work for open(2) on regular files:
The affected system calls include open(2), read(2), write(2),
sendto(2), recvfrom(2), sendmsg(2) and recvmsg(2) on a
communications channel or a slow device (such as a terminal, but not
a regular file) and during a wait(2) or ioctl(2).
I've never observed EINTR from open(2) for a traditional file system
such as HFS+, but it's easy to observe with a fuse file system that is
slightly slow (cf. https://goo.gl/UxsVgB). After this change, the
problem can no longer be reproduced when calling os.OpenFile.

Process.handle was accessed without synchronization while wait() and
signal() could be called concurrently.
A first solution was to add a Mutex in Process but it was probably too
invasive given Process.handle is only used on Windows.
This version uses atomic operations to read the handle value. There is
still a race between isDone() and the value of the handle, but it only
leads to slightly incorrect error codes. The caller may get a:
errors.New("os: process already finished")
instead of:
syscall.EINVAL
which sounds harmless.

cat with syntax coloring.
In that vein, I built this test around smallpox.
