ISSUE:       5606
TITLE:       Trace session leads FB 4.0 to hang after 2nd launch of trivial .sql script. Neither attach to any database nor regular restart of FB service can be done.
DESCRIPTION:
  Ticket issue was reproduced on trivial trace config with single line ("enabled = true").
  We prepare such config, launch trace session in async mode and run THREE times isql with logging its output.
  Then we stop trace session and open isql log - it should contain three 'packets' of table records.
  If FB becomes unavaliable, this (and all subsequent) test will not finish at all.
