Alert slow with callback and large memory reactive

[dkulp2]

If there is a reactive object that is very large then the shinyalert modal is very slow when there is an R callback.

This is a very odd problem and I spent hours trying to create a minimal example. I find on both Linux and Windows that clicking the modal with callback will take over ten seconds to display if the allocated matrix is over a GB. But the modal without the callback is fast regardless.

Here's sample code: https://gist.github.com/dkulp2/f1a773fcf29cfccd788bc7c8b7b35189

Let me know if I can help. This has become a problem with a production app and I'm eager to try to resolve it.
