What Happened?

Activate the symbol pane and then tried to open a .vapi file with about 10,000 lines. Code froze pretty much indefinitely. With smaller .vapi files, 5000 lines tool 2 - 3 seconds to parse but 1 - 2000 lines there was minimal delay.

Steps to Reproduce

  • Activate the right-hand pane (Vala symbols)
  • Open a large .vapi file (e.g. clutter-1.0.vapi)
  • Observe interface frozen indefinitely (freeze may occur after a few seconds depending on resources available and whether editing is attempted before symbols loaded)

Expected Behavior

The Vala Symbol pane should cope gracefully with files with many, deeply nested symbols when resources become short.

It is debatable whether it is necessary to parse .vapi files.  Actual .vala files tend to be smaller and I have not noticed an issue with them.
