The Nightly Routines sending surveys method now operates on its own timer and its own thread. This means that survey sending can happen in parallel with the other processes that run.
Note that at present it is only the survey sending routine that operates in this manner. All other parts of nightly routines operate sequentially.
This means that the survey sending timer will not be held up by, for example, long data pack requests. However, other processes such as Sync Employment group head counts, or survey merging will be held up.
