Untested is right. Your 'del' statement is a little bit too destructive, or 
at least it would be if strings were mutable.

Here's my (equally untested) alternative:

for line in serverIn:
    line = line[:-1]
    if line == "bla":
        do something incredibly interesting
    else:
        print line
