Fixes #2782.  The brtloader uses temp dir.   Note however that #2783 isn't fixed yet. close[t:2782].

 * That's 2/3 of 3/4, which is calculated as 1/4 is unreservable.  The loader asks for 2/3 of what's reservable, getting one half.
The second loader gets 1/6 of cachetable memory.
 * That's 2/3 of 1/4: The loader asks for 2/3 of what's reservable.  1/2 has been reserved.  1/4 is unreservable.  1/4 is reservable.  2/3 of 1/4 is 1/6.
The third loader gets 1/18 of cachetable memory. 
 * That's 2/3 or 1/12.   (1/4 is unreservable. 1/2 was reserved by the first loader.  1/6 by the second.  That leaves 1/12)
Generally the next one gets 1/3 of what the previous one got.
