wdrain appears to be associated with file I/O rather than paging
(though I may be wrong here).  Is it possible that vim had started
core-dumping before you SIGKILL'd it?  I've seen problems on other
OS's where core-dumping processes couldn't be killed and caused
significant performance degradation if they were very large.
