<pre>We should pause and resume the database thread when the UIProcess enters and leaves the background, respectively, to avoid WebProcess termination due to holding a locked SQLite database file when the WebProcess is suspended.
Analogous behavior is implemented in Legacy WebKit. See <<a href="http://trac.webkit.org/browser/trunk/Source/WebKit/ios/Misc/WebUIKitSupport.mm?rev=176347#L113">http://trac.webkit.org/browser/trunk/Source/WebKit/ios/Misc/WebUIKitSupport.mm?rev=176347#L113</a>>, <<a href="http://trac.webkit.org/browser/trunk/Source/WebKit/ios/Misc/WebUIKitSupport.mm?rev=176347#L118">http://trac.webkit.org/browser/trunk/Source/WebKit/ios/Misc/WebUIKitSupport.mm?rev=176347#L118</a>> and <<a href="http://trac.webkit.org/browser/trunk/Source/WebKit/mac/Storage/WebDatabaseManager.mm?rev=180704#L291">http://trac.webkit.org/browser/trunk/Source/WebKit/mac/Storage/WebDatabaseManager.mm?rev=180704#L291</a>>.</pre>
