With Phobos, std.gc.malloc is supposed to return uninitialized data.  Here's 
a little template function to make it easy:

import std.gc;

T[] allocUninit(T)(size_t len)
{
    return (cast(T*)std.gc.malloc(len * T.sizeof))[0 .. len];
}

...

auto arr = allocUninit!(char)(512);

The equivalent in Tango is GC.malloc from tango.core.Memory.
