I don't think so.
on windows I have "implement" inside of VSDK cooperative multi-tasking using
one global semaphore.
This means that you can have 10 own threads in your app, but access to
database will be semaphored.
I am going change this soon.
So you want do LONG write into BLOB and in the same time work with other
