In my plugin I created a custom Markers View to display only specific
markers (in this case notifications about test failures). However, I can't
make it to update as soon as markers are added/removed. It is visible
immediately in editor (the marker icon appears/disappears from the bar
next to line number) and in the PackageExplorer view (the error icon
appears/disappears on related project), but my custom view has to think
for quite some time before it shows current state. Therefore, I'd like to
ask if there is any way to manually refresh custom markers view or at
least shorten the amount of time it takes to refresh itself.
