They return a new class instance every time (BurstJobHandle in the case of the Burst backend), and I see this is conceptually necessary because there are two backends and the shared interface IObiJobHandle is used. However, both those classes are so simple that I don't think this deserves an allocation each and every frame.
For my project, I added a pool for the burst job handles now, which I release before the Clear that @timconkling added. This gets rid of regular allocations and does not need much refactoring (I added a Release method to the IObiJobHandle interface). Something like this should definitely be adopted in Obi.
With this change and the others I proposed (http://obi.virtualmethodstudio.com/forum...-3251.html and http://obi.virtualmethodstudio.com/forum...-3250.html), I seem to be down to zero per-frame GC allocations for Obi.
Hi pdinklag,
Thanks a lot for your reports/contributions! This one and the allocation in Decimate() will certainly make their way onto Obi's codebase.
Keep an eye for them in Obi 6.3.1.
