Not in kernel but userspace, seems like Linux:
http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/dynamic_pager.8.html
The dynamic_pager daemon manages a pool of external swap files which the
kernel uses to support demand paging. This pool is expanded with new
swap files as load on the system increases, and contracted when the swap-swapping
ping resources are no longer needed. The dynamic_pager daemon also pro-provides
vides a notification service for those applications which wish to receive
notices when the external paging pool expands or contracts.
