  -----------
  [Debug] Referencing `m_processPool` in `~WebProcessProxy()` causes a crash
https://bugs.webkit.org/show_bug.cgi?id=264178

Reviewed by Chris Dumez.

Cached `WebProcess`es can be destroyed as a result of clearing
`WebProcessPool`'s cache during its destruction.

In this case, referencing `m_processPool` will fail because its deletion
has already begun.
