hoon: sort runs out of memory

[yosoyubik]

> =+  (gulf 0 11.384)  =+  (sort - lth)  (lent -)
11.385

but

> =+  (gulf 0 11.385)  =+  (sort - lth)  (lent -)
(recover: dig: meme)

This looks like something wrong with the sort jet.

Another data point, ++skim works fine:

> =+  (gulf 0 111.386)  =+  %+  skim  -  |=  a=@  &  (lent -)
111.387

Looked at this one together with @pkova
