SIGSTOP on a cbbackup causes view indexing to hang

Setup

• 2 node 4.5.1 cluster (used vagrant), single couchbase bucket
• 100K docs @ 512 bytes, 1 replica
• Run a backup using the invocation below. When the UI shows the "Other" DCP connections, CTRL+Z it on the command line (to cheaply simulate a cbbackup hang)
• Do this twice more for good measure
• Create a default production view (just the basic emit) and publish it
  Behaviour
• The design document doesn't get indexed
• Resuming the backups (by foregrounding the jobs) and allowing them to complete then allows the design document to be indexed.

cbbackup invocation:

/opt/couchbase/bin/cbbackup -m full -u Administrator -p password -t 5 -x cbb_max_mb=100,report=1000,report_full=100000 couchbase://localhost:8091 /tmp/backup
