If an astronaut in the vacuum of space released a bag of flour, would the powder stick onto him/her?

You know...due to gravitational pull, since the human body (and the space suit) would proportionally weight a lot more than a speck of flour.  This is also assuming there are no nearby objects with a greater gravitational pull.

Edit: Wow, thanks for the detailed answers.

Edit 2:  I was thinking more along the lines of if static, initial velocity from opening a bag of flour and so on were not a factor.  Simply a heavy object weighing 200ish pounds (human body with suit) and a flour specks with no initial momentum or velocity.  It is good to know gravity is a very weak force though.  Thank you all. :)

Intermolecular forces like electrostatic attraction and Van der Waals forces would be much much more significant than gravity for these small particles. In fact, the first dust bunnies that started coalescing when the solar system formed and would eventually become planets were first attracted by these weak forces, not gravity.
