Bug 178527 – Service Worker process should not be selected to open WebView on it

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[youenn fablet]

Currently service worker process is a web process.
In the future, we might want it to have a dedicated type.
In the meantime, it should not be selected to open WebView on it

I think processes is too generic, how about reusableProcesses ?

You're going to need to protect the second check behind a #if ENABLE(SERVICE_WORKER)

I would call this processToReuse. LGTM otherwise.

This is a crash fix which was split out of Bug 178475. When Bug 178475 lands, if API tests and layout tests do not crash, then this patch works as intended.
