i attached a small test tool, that also use odbc to get the same busy blob
file from the same DB i use. With this test tool. id does not crash,
although it fetches much more blobs from the DB, then with res_odbc.

What is the difference between the way the test tool fetch the blob and
res_odbc/app_voicemail_odbc? The test toll get's the blob in sequence.
Perhaps res_odbc/app_voicemail_odbc fetch it parallel, and this is the
problem? (my assumption)
