tmpfs size option not working

Hello,
I'm trying to fix the maximum size of a tmpfs (my /var directory) but
the size=16m option doesn't seem to work. The corresponding line in my
fstab is : 
none /var        tmpfs   size=16M   0   0
But if i create a big file under /var I never receive any error message
telling that the limit has been reached. For example if I do a

$ yes BlahBlahBlah >> /var/test

the file /var/test becomes after a while much larger than the 16MB limit
I've set and finally uses all the RAM...

I've tried to unmount and remount /var manually after startup with 

$ umount /var
$ mount tmpfs /var -t tmpfs -o size=16m

But the result is the same. The limit is not respected...

Any idea?

Thanks,

julien
