Everyone thus far has recommended file locking. Another way is to create a new file
for each vote, naming the new file with a date/time/microtime with each vote.
You start or end the file name with something unique (a number or letter, etc) to
each answer, OR, put the file in a particular directory depending on the answers.
Then, it's easy to count how many people voted a particular way just by counting the
number of files. For example, at a unix type command line, you can type
"ls | wc -l"
