Subject: net_native: close() should not block
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=3a4dacd7e1d7706814e52f9571ec7534f1533627;p=FUZIX.git

net_native: close() should not block

The close process is supposed to go on asynchronously behind the back of the
closing process.

This is important because we are going to stop processes from sleeping during
an execve()
