Stop using OSv-specific features (namely debug()) in this test, so we
can also run it on Linux.
This test currently hangs on Linux, because the test assumes that signal()
sets system calls to not restart - while on Linux, they do.

reservations on that patch, which is why it wasn't committed.
Did you also try more recent versions and failed? Or did you really want to
run 6.10 in particular?

This patch simply removes libosv.so from the java module. Nothing seems
to rely on it.

That's great!
With the patch I sent yesterday allowing a kernel of any size, you should
now be able to run any OSv image when built with fs=ramfs
this as a "TODO" and only go back to it after you make the network (for
example) work.

Hi, sorry for the belated review.
There's a lot of stuff here. Do you need all of that just for the "hello
world" example, or are you adding much of it in anticipation of the
network/disk support later?

Fixes #878, but openjdk8-fedora+tomcat still does not work, because
of yet another bug.

the entire readv() scattered buffer, as expected.
So we don't need this workaround, which can only hurt performance, and in
the present case, prevent fread() from working on a block device.
Fixes #877

If you tried to read a non-existant file, it should have also failed this
way previously, and not with an assert.

We saw these 100ms "hangs" of TCP sessions in real benchmarks of nginx,
because its usage of TCP_CORK was silently ignored.
Fixes #883.
