dynamic_paging
I noticed on my MacBook Air that after a few weeks I would run out of diskspace, without downloading anything, forcing me to reboot. Before I did, I checked /tmp and nothing looked large enough. Bryan F from [yh] pointed out "man dynamic_pager"
$ ls -la /private/var/vm/swapfile $ sysctl vm.swapusage
I noticed gigs worth of files! At your own risk:
$ sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
and reboot. After reboot, sysctl vm.swapusage shows 0 and /private/var/vm/swapfile is empty. replace "unload" with "load" above to revert to default.
