f53a5e569d Configuring awl pool to give give up and scan an entire segment after 200 single access hits, after observing open dylan bootstrap on ubuntu 12 hammering the table and making no progress. 
AWL pool no longer tries a single access if the trace band has reached rank WEAK, since it doesn't need to.

e3c37ff15e Mps br/diag: diag-out with writef and diag_stream does not work in cet. 
Hope to fix in time, but for now I need DIAG-out to work, so switch 
to printf (yes, really, I know, sorry).
Also, only do DIAG-out in variety.di, to avoid damage to .ci.
So for now, remove DIAG_WRITEF and DIAG from arenavm and trace.
To test, add DIAG_PRINTF in trace.
