Issue Description

Auto-complete was working for about 5 minutes into editing a small script (220 lines) but now it has wedged.

Expected Behaviour

Auto-complete should not ever stop working - in an ideal world. :-)

Actual Behaviour

I get the dreaded "Loading..." message for at least a minute before I give up:

Does Ctrl+C help?

[rkeithhill]

In the integrated terminal? For some reason, the integrated terminal is not appearing in my list of terminals.

[rkeithhill]

Also, seems my PS Session is still using RC.3 even though I upgraded to the GA release.

[rjmholt]

It's probably defaulting to preview. Try switching to PowerShell (x64)

[rkeithhill]

OK, now on PS 7 GA and have PSIC displaying. I had done some experimenting with settings a while back and apparently set showOnStartup to false. Fixed.

[rjmholt]

Are you running anything in the time before the completions fail?

[rjmholt]

I'm getting sluggish completions, but haven't been able to repro this yet

[rkeithhill]

No, not running anything. I can do a develop reload window and try auto-completion and initially, it works OK but gets slower. Some context, these couple of PS scripts are in a project that houses an Electron app with several Angular lib projects. That's six node_modules directories and 295,000 files.

[rjmholt]

That's six node_modules directories and 295,000 files.

Wow. Hmm yeah I suspect this is related to that. I think there might be a simple fix here that we've been overlooking for a while, where we need to filter out bad files...

I'm thinking of #1256 (comment)

[rjmholt]

That just encourages me to get back to work on PSScriptAnalyzer...

I'm also getting a slow down on auto-complete. Even with a project containing only a few files.
