How realistic is it to run processes of this OS (like the netstack processes) on top of existing microkernels like minix/QNX/etc. ?

Why is the tcp socket set to busy poll for 1 microsecond?

> ICMP is dangerous, and needs to be blocked I've fought this argument countless times and lost. Not being able to ping a server, check for "destination unreachable" messages, etc.…

Small additions here: the networking components of QNX moved to kernel space quite some time ago, I don't even know if io-net is still supported. As far as I know they've reused th…

For my job I had the opportunity to work with quite some OSI standards on top of TCP/IP (X.216, X.227 and X.500, X.400 as application layers). My experience is quite in line with t…

True that, but I was talking about the POSIX async I/O API: http://pubs.opengroup.org/onlinepubs/009695399/basedefs/aio.... I don't know much about the LinuxThreads-era.

But that's the thing: places which fit those requirements usually run some IBM solution (AS/400 and the likes). I've never encountered VMS in production before, so I'm really curio…

Could you elaborate on how it did things better than the common cluster file systems of today? (OCFS2, Hadoop, Ceph, etc.)

Could you give an example of such an industry? VMS to me has always been that OS that everyone claimed to be better than UNIX-likes, but none could explain why.

That's not really a fair comparison: Windows I/O completion ports are a proprietary standard that is part of the NT kernel, while POSIX AIO is just a user-space libc extension that…
