Intent would be to reuse the OutBuffer, but without reallocating memory
for the buffer.

Currently not possible. Enhancement request perhaps?

Looking at the implementation, setting its 'offset' member seems to 
work. Based on example from documentation:

import std.outbuffer;

void main() {
    OutBuffer b = new OutBuffer();
    b.writefln("a%sb", 16);
    assert(b.toString() == "a16b\n");

    b.offset = 0;
    b.writefln("a%sb", 16);
    assert(b.toString() == "a16b\n");
}

Bug report perhaps? :)
