I believe clean may be ok, unless there's a ton of WeakReferences getting collected. clean repeatedly polls the ReferenceQueue for any collected references, removing them from ObjectSpace. According to JavaDocs and the 1.5
ReferenceQueue implementation, each poll should just pull the 'head' item o

Hi,
Regardig the ObjectSpace-implementation, I would recommend you to move the
cleanup call to ObjectSpace#iterator() ... I think that's where most of the
performance go through the roof.
And it's not like those WeakReferences are a problem...

FYI, the ObjectSpace performance hit appears to come from its use of a synchronized Set. If I modify it to use an unsynchronized Set, the numbers approach those when I have it completely disabled. Who says synchronization costs nothing?
The ObjectSpace thing is particularly interesting since it wou

Some notes on performance exploration. Most of this is based on my belief that our core interpreter and the core native types (strings, symbols, fixnums, etc) are a large source of our performance woes. C Ruby is able to use extremely lightweight structs for most of these core types, and runs blazi
