( #3333=superdoc: print w/ replies, xml ) Need Help??

Along the same lines of what halley had to say in his reply I once solved that problem by using an algorithm described in the following psuedocode:

open file for reading slurp in file into a scalar close file calculate the MD5 of slurp buffer wait X seconds open file for reading slurp into second scalar close file calculate MD5 of second slurp buffer compare and repeat if not equal.
Another scheme I have used in the past is to let the FTP client that is putting the files into the directory bit-twiddle the permission bits so that when the client is done copying the permission bits are of some pre-agreed upon value, (444 being my favorite) and then opening the file.
