What's the equivalent of sleep(), wait(), or pause()

[James Pelcis]

In this case, the best solution would likely be std.c.time.

# private import std.c.time, std.stdio;
#
# void main () {
#	writefln("Hello World.");
#	sleep(2);
#	writefln("Goodbye World.");
# }

I don't know of any pure D ways to do this in Phobos.  The closest I 
could think of is in std.thread and is specifically prohibited...

# private import std.thread, std.stdio;
#
# void main () {
#	writefln("Hello World.");
#	std.thread.Thread.getThis.wait(2000);
#	writefln("Goodbye World.");
# }

I don't know why that is though.  My guess would be it's to cover up 
limitations in the operating system thread implementations.  Can anyone 
confirm that?
