To thread or not to thread

My app needs to check a number of things on the web. This can be done in the
background.
I use idHTTP to pull data in. This process is broken down into small parts
and the subroutinen are called in the OnIdle handler of the main form.

I notice that sometimes idHTTP needs a considerable time to build the
connection/fetch the data and the application doesn't repond to user actions
during such periods.
To cope with this I have now implemented the web data fetching in a thread
with priority tpIdle. I think the problem of non-response has gone, ut it is
difficult to test.

Am I right in assuming that the statement
document:=idHTTP1.Get(someURL);
in the thread should be less disruptive to the user than the same call in
the OnIdle handler ?

TIA
Tom
