The most important change in this release is the removal of the poll_fd() system call; CloudABI's equivalent of kevent(). Though I think that kqueue is a lot saner than many of its alternatives, our experience is that emulating this system call on other systems accurately isn't easy. It has become a complex API, even though I'm not convinced this complexity is needed. This is why we've decided to take a different approach, by looking one layer up. We're currently adding an event loop to CloudABI's C library that is API compatible with libuv (except when incompatible with Capsicum). Initially, this event loop will be built on top of plain inefficient poll() calls. Only after this is finished, we'll work our way backwards and design a new set of system calls to optimize it. Interesting challenges will include integrating asynchronous I/O into such a system call API. libuv currently doesn't aio(4) on Linux/BSD, due to it being unreliable and having undesired semantics.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
