Synchronous FTP upload?

[Richard Gaskin]

Dave Cragg did a great job with the new libURL, but I need something that
doesn't seem to be supported:

How can I upload a file synchronously, such that all scripts stop until
either the file is uploaded successfully or an error is encountered?

I have a fairly complex setup in which I nee to avid race conditions, and
using "put" seems to allow processing of other messages while it's
connecting and uploading.

Thanks in advance -
