LimeWire will redownload files after verifying if it detects that a part of the file was corrupt. Verification will only begin after LimeWire has downloaded 100% of the file. After verification, LimeWire will either proceed to save the file or redownload the parts that were corrupt. LimeWire will attempt to recover from corruption up to 6 times before giving up and just leaving the file as corrupt.

A future version will change this so that verification takes place as the download is happening.

Those folks in the chatroom are just trying to annoy people -- dropping off the download when it's 99% or so does nothing other than annoy people who can't get that last 1%.
