Commit in pl/sql procedure returning control too soon?

 Hi, I have DEV DBA, who wrote a pl/sql stored procedure that contains 

FOR 

    inserts into a single table (inserts a list of school id's)

LOOP 

COMMIT;

dbms_scheduler.create_program...

dbms_scheduler.DEFINE_PROGRAM_ARGUMENT...

DBMS_SCHEDULER.create_job...  --creates and runs a job that does stuff to each school id in the list that was inserted in the table in the above for loop

However, the DEV DBA says that the job is working for all the schools except for the first one.  They think that the commit is in the background and the procedure control continued on and created and executed the job before the commit finished, thereby missing the first school.  This behavior only seems to happen with large data on an under-powered box (its under stress). But, still, the commit should completely finish before continuing in the code - right?
