One problem with allocating the exception is the stop-the-world 
thing. My cgi.d's built in httpd does some allocations in its 
constructor, which is run once per request. It can answer 
requests at a rate of about 6000/sec on my computer...

Until the allocation have gone too much and the GC starts 
running. Then all the pending requests stop, killing the 
throughput.

(BTW, interestingly, on Linux it uses separate process pools 
instead of threads. The GC does NOT stop the world since the 
other processes can keep going. But, if the requests are fairly 
uniform - as is typically the case with benchmarks - each process 
hits the GC threshold at about the same time.... ironically, it 
is the deterministic nature of the GC that leads to the 
performance killer there.)
