> "Cutler’s vision finally pays off after 3 decades of waiting."

Quite!

But only because the Interix-derived POSIX subsytem was, and is, little-known and vastly underappreciated. Had it been better known, the payoff might have come a decade or more sooner. There are a fair number of questions being asked now, about the new Linux subsystem, where the answer is "No; but the old POSIX subsystem had that.".

* Does it support pseudo-terminals? No, according to the demonstration video; but the old POSIX subsystem did. (https://news.ycombinator.com/item?id=11415843)

* Does it let you kill Win32 processes? No; but the old POSIX subsystem did. (https://news.ycombinator.com/item?id=11415872)

* Does it support managing daemons? No; but the old POSIX subsystem did. (https://news.ycombinator.com/item?id=11416376)

* Does it support GUI programs? No (say the people behind it themselves, although I suspect that it could run X clients); but the old POSIX subsystem did. (https://news.ycombinator.com/item?id=11391961) (https://technet.microsoft.com/en-gb/library/bb463223.aspx)




I remember having a Microsoft developer (I'm afraid I forget her name — Six?) come and visit us several years ago to demonstrate the then-new SFU 3.0.

Seeing her send SIGSTOP to a running MSWORD.EXE process and observe it stop updating its window in response to expose events was splendid. :-)
