Hello all.<br>
Had a thought for improving ruby&#39;s GC the other day.<br>
<br>
Currently it&#39;s<br>
<br>
*stop world*<br>
mark<br>
sweep<br>
*start world*<br>
<br>
suggestion:<br>
<br>
*stop world*<br>
mark<br>
sweep a little bit<br>
*start world*<br>
finish sweep in another thread.<br>
<br>
(Obviously there&#39;s be some ramifications, like having to add some<br>
locks here or there, and doing some thread joins, but hopefully that<br>
wouldn&#39;t cost too much cpu-wise).<br>
Thoughts?<br>
