Why are so many git processes being launched in the background?

After commenting on this on ticket SRCTREEWIN-2038, I checked what is going on and it doesn't feel right.

I have disabled "refresh automatically when files change" and I see git being started 3-4 times within a second. These are the commands being executed all the time, for the different repositories:

status --porcelain --untracked-files=all --ignore-submodules=dirty
show-ref --head --dereference
remote -v
branch -r
stash list
rev-parse HEAD^1
branch
branch -vv
rev-parse HEAD

Some commands are execute for the same repository several times in a row, within the same second. Is this really necessary? Shouldn't this be checked only when refreshing?

I gahered the information using ProcessMonitor from Sysinternals, setting a filter for showing only "start process" events and with parent id = sourcetree's.
