Yes, you can execute a modal dialog without using exec().

>From http://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WDialog.html:

WDialog can be used as any other widget. In this case, the WDialog is
simply instantiated as another widget. The dialog may be closed by
calling accept(), reject() or done() (or connecting a signal to one of
these methods). This will hide the dialog and emit the finished()
signal, which you then can listen for to process the dialog result and
delete the dialog. Unlike other widgets, a dialog does not need to be
added to a parent widget, but is hidden by default. You must use the
method show() or setHidden(true) to show the dialog.

So, instead of exec(), use show(), and listen to the finished() signal
instead of inspecting the result of exec(). This does mean that you
cannot build your dialog on the stack, and for a complex dialog you
will want to specialize WDialog to keep track of form fields. See for
example FileEditDialog in TreeViewDragDrop.C (treeview-dragdrop

In the mean-time we have been brainstorming about solutions to the
original problem. One solution would be to not spawn a dedicated
thread for each session, but instead make it so that a session is
always handled by the same thread (by using a hash function on the
session ID which hashes it on a thread from a thread pool). However,
we currently do not see how this can be done in conjunction with our
current asio design for wthttpd.
