(I hope my english won't be so bad, cause I'm french)

I have a website that uses your module. But I accidentaly pressed many times my return key after filling a profile page (just after creating the user account).
Now I have 3 entries in my database of the same profile, and my page shows me as many links as times that I pressed the return key.

I saw that profile2 controls whether a profile exists before adding it, but if the validation is too fast, all queries will be run, because the database stays empty.

Is it possible to disable the form submission after one submission ?
