  Bug#21721 Test suite does not start with NDB, hangs forever; problem around "ndb_mgmd"
   - Wait for ndb_mgmd with timeout

  mysql-test/mysql-test-run.pl@stripped, 2006-08-31 10:28:45+02:00, msvensson@shellback.(none) +20 -4
    Add new function 'ndb_mgmd_wait_started' that will wait with timeout until ndb_mgmd has been started
    Don't bother to save the return value from 'ndb_mgmd_start' in local var as it's not used.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
