I did only first research. Any hack is possible - you can stack
current transaction, but real implementation needs similar work like
nested transaction :( and it is too low level for me. And some code
cleaning is necessary. There are global variables.

And there is most important question about data visibility - is
autonomous transaction independent on main transaction (isolation)?
You have to thing about deadlock, about reference integrity, etc. This
task isn't simple.
