Big iNode file in lost+found

I recently went through a difficult install of Lion (Fried my RAM). I basically wiped my Hard Drive, installed clean from a thumb drive, created a new user profile, then used migration assistant to move my time machiene files and old user profile over. The only thing that went wrong with this was that my old migrated profile would crash upon start-up, but this went away once I let the system index with my new profile.

Cleaning up after this mess, I saw a lost+found folder was created, and an iNode was in there (iNode290815 to be precise). Read what this meant online, and ran disk repair. It seemed to fix whatever problems may have been left over from the install, but the iNode file is still there, and it's 3.6 gigs large. Since Disk Repair checked out, and everything has been running well, is this file ok to delete? I'd like the space back, if possible, or at least move it so its out of sight.

Thanks
