I concluded this from former tests allocating lists. I've now also 
tried to run my stream benchmarks on Bigloo, and have realised that 
Bigloo (C backend, with -O or -Obench) is about 2 times slower 
processing them than Gambit, and worse, the stream heads are not 
reclaimed while walking the streams (*), so Bigloo runs out of memory 
on the same code which is processed in constant memory by Gambit or 
Chicken. I'm sending a copy of this mail to the Bigloo mailing list: 
please tell me if there's a solution to this problem.


(*) with code like: (stream-length (stream-iota 10000000))
or more precisely: see code at
