"small freeze in a small module after ctrl alt l to remove an import"
===

3000 ms CPU time on EDT

    1400 ms is spent in native AWT UI methods
        400 ms - sun.awt.windows.WGlobalCursorManager.findHeavyweightUnderCursor[native]
        300 ms - sun.awt.windows.WGlobalCursorManager.setCursor[native]
        300 ms - sun.java2d.loops.FillRect.FillRect[native]
        200 ms - sun.awt.windows.WComponentPeer.getLocationOnScreen[native]
        100 ms - sun.java2d.loops.MaskFill.FillAAPgram[native]
        100 ms - sun.java2d.loops.DrawGlyphListLCD.DrawGlyphListLCD[native]

    1400 ms - KotlinImportOptimizer$OptimizeProcess.execute()
        700 ms - collectDescriptorsToImport()
            300 ms - KotlinScriptDependenciesClassFinder.findClass()
        600 ms - prepareOptimizedImports()
            200 ms - GlobalSearchScope$FilesScope.contains() [NOTE: fixed in 2019.1 merge]

Caveat: 100 ms sampling interval for 3000 ms freeze
    => slightly noisy results

"very long freeze in the main module + wait until the full analysis is made after ctrl alt l to remove an import"

26000 ms CPU time on EDT

    21800 ms - KotlinImportOptimizer$OptimizeProcess.execute

                8200 ms - kotlin.LibraryWithoutSourceScope.getFileRoot

"very long syntax coloring + analysis when opening a large file"
===

24s CPU time on FJ pooled threads (which are used for syntax highlighting)
But, 100s real time. Suggests non-parallelized work or lock contention.
    Of this: 18s CPU time / 70s real time in kotlin.ModuleResolutionFacadeImpl.analyze
[NOTE: real time is accumulated per thread, and there are over 10 FJ pooled threads]

Related: 43500 ms real time in LockBasedLazyResolveStorageManager$LockProtectedContext.get
    But only 1900 ms CPU time.

No calls to KotlinScriptDependenciesClassFinder in this one.
