I do not want to set the concurrency flag in activerecord to true for  
a variety of reasons. My ROR appln has a background thread spawned  
which accesses the DB and send out an email. When this background  
thread is accessing the DB, if a web request comes in ( that calls for  
DB access) then we have 2 threads on the same ActiveRecord connection.  
I dont mind synchronizing the access to the DB. . But not able to find  
where I set that flag…

From a different perspective, I guess Mysql JDBC driver synchronises  
the packet sending over TCP connection, so even if multiple threads  
use the same connection in JAVA you are still safe ( nothing to do in  
application code).

How do I get a similar functionality in ROR.?
