Patch to try - Re: Sendmail rset command hangs socket on 1.6-Release

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    Please try this patch and tell me if it works.  I think we have an issue
    when one process holds an exclusive lock while 2 or more processes are
    trying to get a shared lock, or vise-versa.
