Hello, I had uploaded a portable Wait For Multiple Objects based on Boost Thread in the vault. Few months ago a memory leak was reported and I finally fixed it this weekend. If you're one of the few people using it, you can download the new version from http://www.boostpro.com/vault/index.php?action=downloadfile&filename=wfmo.zip.
