druntime has a small benchmark suite in druntime/benchmark. I'd be very 
interested to see how it performs against this. (Some files are from 
Leandros tests.) Just compile and run "runbench.d".

I'm benchmarking my Windows version of a concurrent GC with it. It does 
quite a lot of allocations, and this is causing some serious trouble 
because marking cannot compete with the rate of allocation, causing some 
tests to allocate a lot of memory, slowing down marking even more. I'm 
still looking for a solution...
