Bug:Rusticl: segfault on waitForEvents(clEnqueueUnmapMemObject) in finalize

For some reason, waiting on the event object returned by
clEnqueueUnmapMemObject, but only when called from within finalize().
Under normal operating conditions when we map and then unmap our
HOST_PTR buffers, everything works just fine.

I can't discern any relevant difference.
Adding a bridged 300ms delay in setup() doesn't help either so it
doesn't seem to be solved by allowing the rusticl worker threads
to finish initializing.

GDB output from the segfault appended. Sadly, no debug symbols for
the ubuntu rusticl package.
