As James answered already ... transaction management of multiple sub processes within one gem can get very difficult and may lead to pretty difficult to find errors.
We have done a project around 1997-2005 with VA and Versant as an object oriented database and also had lots of sub processes and it took very much time to find all the errors in this structure.
So unless you know what you are doing ... try to live with one transaction process within one process

Ciao.
I started a gem session with topaz.
After in this session i run some sub processes: [...................] forkAt: 25
each of which with a tcp-ip connection read the data from a printer device,
checking that the responses received are consistent with the data sent to the device.
At this point it is not clear to me how each sub-process manages the transaction with commit or abort.
Any sub process is independent from this point of view?
Any reference, indication?
Are there any limits to the number of subprocesses (forkAt:) that the system - a gem session can handle?
Thank you,
Dario
