e486078a79 Mps br.timing: testlib randomize() was wrong (simply discarding the first 0..32000 values is a throughly defective way to seed the generator). correct it to simply use timestamp (modulo m) as the initial seed, and then iterate 10 times. 
rnd(): add notes, and create rnd_verify() to confirm implementation is correct.

4fc1ea19fb Mps br/timing zcoll.c: show count of objects made & kept. 
Also (TEMPORARY) investigate poor seeding of rnd().  Aha -- 
it's a full-period generator.  Therefore the current 
randomize is a very poor way to seed it.

eb1cca20e4 Mps br/timing z001989a.c: timca_remote -- traceidmessagescreate alloc remote control 
In low memory situations, ControlAlloc may be unable to allocate 
memory for GC messages.  This needs to work flawlessly, but is 
hard to test.  To simulate it for testing purposes, do macro-magic 
in traceanc.c, before the definition of TraceIdMessagesCreate.
Test all designed behaviour of TraceIdMessagesCreate failing.
See <design/message-gc#lifecycle>.

yet test finalization messages.  But works, so useful checkpoint.
