Hi,


are there any plans to(optionally) lock memory to RAM e.g. via memctl() 
in order to avoid
paging during GC runs?
IMO this becomes more of an issue (and not less) the bigger applications 
become and the
bigger heaps get sized. With a small heap of 1 or 2 G paging was rarely 
an issue. With a
heap of 10 or 20 G paging is more often observed than one might think.

Thanks and Regards

Thomas
