You are certainly under effect of BLODA.
You could have a look (there is a BLODA section in Cygwin online doc).
Then, when (bash) scripting under Cygwin, you must take care to avoid
forking as much as possible.
You could try to improve the "sleep 1" loop with the following one :
while md5sum $FILE_TO_CHECK | cut -d " " -f1 | grep -q "^$MD5PRINT$"
Note that MD5PRINTNEW is no more useful here.
With this loop we avoid the fork done by
MD5PRINTNEW=`md5sum $FILE_TO_CHECK | cut -d " " -f1`
