dbaccess::ODatabaseContext cleaning its cache "too late"?

Happened to notice on current master that "File - New - Database - 
Select database - Create a new database - Embedded Database: HSQLDB 
Embedded - Finish - Save - Use Wizard to Create Table... - Cancel - File

other UNO services (like the TempFile one) are already disposed when the 
dbaccess::ODatabaseContext service impl is disposed and in turn disposes 
its cached datasources, which in turn appear to always call 
commitStorageIfWriteable_ignoreErrors.

No real insight into any of this, but would it make sense to rely on 
some explicit "commit" stimulus to do that committing, instead of doing 
it upon "dispose" (or at least take into account m_bModified and not try 
to commit if not necessary?).
