Title:
  gpg --verify has race conditions when used concurrently

Status in “gnupg” package in Ubuntu:
  New

Bug description:
  There is a race condition with gnupg --verify when multiple processes
  act at the same time.
  strace helps cause the race condition (probably by slowing thing down)
  gpgv does not seem to have the issue.

  The result is you will see transient verify failures with output like below.
  using '--lock-once' seems to improve the problem, but not to entirely fix it.

  gpg: Signature made Fri 10 Jan 2014 05:41:43 PM UTC using DSA key ID 437D05B5
  gpg: 12: read expected rec type 10, got 0
  gpg: lookup_hashtable failed: trust database error
  gpg: trustdb: searching trust record failed: trust database error
  gpg: Error: The trustdb is corrupted.
  gpg: You may try to re-create the trustdb using the commands:
  gpg:   cd ~/.gnupg
  gpg:   gpg2 --export-ownertrust > otrust.tmp
  gpg:   rm trustdb.gpg
  gpg:   gpg2 --import-ownertrust < otrust.tmp
  gpg: If that does not work, please consult the manual

  See the attached 'verify-race' to show the issue.
