Please fix EWS build failures.

> Source/WebKit/NetworkProcess/Downloads/Download.h:103
> +    friend class DownloadMonitor;
>      bool isAlwaysOnLoggingAllowed() const;

Can we just make this interface public? Seems less bad than making all our data members public to DownloadMonitor.

> Source/WebKit/NetworkProcess/Downloads/DownloadMonitor.cpp:86
> +    while (m_timestamps.size() > maxTimestampsSize)
> +        m_timestamps.removeFirst();

Can we do this before the append, to avoid out-of-line storage?

Does this need to be a loop, or can we just remove one when we're at capacity?

> Source/WebKit/NetworkProcess/Downloads/DownloadMonitor.cpp:97
> +void DownloadMonitor::applicationNoLongerInForeground()

Let's call this applicationEnteredBackground.

> Source/WebKit/NetworkProcess/Downloads/DownloadMonitor.cpp:116
> +        RELEASE_LOG_IF_ALLOWED("timerFired: Download reached threshold to not be terminated (id = %" PRIu64 ")", m_download.downloadID().downloadID());

So, if you survive past 60 minutes, you survive forever? Is that how other downloads behave?

> Source/WebKit/NetworkProcess/Downloads/DownloadMonitor.h:53
> +    static constexpr size_t maxTimestampsSize = 10;

Let's call this timestampCapacity.

Nit: You can resolve the small differences in these names.

applicationEnteredForeground => applicationWillEnterForeground
applicationEnteredBackground => applicationDidEnterBackground

> Source/WebKit/UIProcess/API/Cocoa/_WKProcessPoolConfiguration.h:72
> +@property (nonatomic) NSUInteger downloadMonitorSpeedMultiplier WK_API_AVAILABLE(macosx(WK_MAC_TBA), ios(WK_IOS_TBA));

Maybe put "ForDebugging" on the ends of this name and its related names, to clarify the purpose.
