Soprano 2.7.4 released

Soprano 2.7.4 is another bugfix release in the 2.7 series:

  • Enabled large file support (_FILE_OFFSET_BITS=64) to fix large DB file locking on 32bit machines.
  • Do not use an event loop when waiting for Virtuoso to initialize.
  • In the socket client: simply close the connection in case of a timeout. We cannot recover from it anyway.
