 Description   

Hello,

We are making large aggregate queries using $allowDiskUse most of the time, and I thought it would be nice to be able to change the fixed threashold of 100Mb in order to use more RAM during large operations.

For instance, I'd love to dedicate 1Gb of RAM per aggregate instead of automatically use the disk as soon as I reach 100M usage.

Thanks for your input on this matter.
