Working on a pre-existing interface that I am not allowed to change, which uses a va_list argument. The method takes way too long to execute and is a canidate for splitting off into another thread. However, I am not sure how I can safely copy the va_list without actually processing its real components. The processing into its real components is a good chunk of what is taking too long.

Any ideas on how to safely pass a varibale argument list to another thread to be processed?
