I'm not sure what I changed in my setup, but I'm getting two new results recently; one I like, the other not so much.

In an iESS R buffer, when I type the name of a function (usually a function in core R) and then a left parenthesis, ESS seems to go figure out what the parameters to that function are, and show them in the minibuffer.  That's handy.  But it seems to sometimes take a really long time, e.g. around half the time I type a function name, it goes away (seemingly hangs) for 10-60 seconds before I can type interactively again.  It's unresponsive to a C-g or C-c C-g.

How can I find out what's causing the delay and squash it?

By the way, when I chose "Send bug report" from the iESS menu, the message it generated was 79,787 lines long, and over 1MB.  I thought it wise to avoid sending that, so I'm sending this manually.
