r35761-2hybrid. WebPositive is able to trigger vm_soft_faults easily.
revisions 265, 272, 283 of Web+ were tested and all behaved in the same
manner. When navigating to most sites, www.haiku-os.org, www.engadget.com,
Web+ will crash, with syslog/serial debugging capturing either of two
error messages
