Hi!

http://dev.mysql.com/doc/refman/5.0/en/innodb-parameters.html#sysvar_innodb_lock_wait_timeout

Documentation says:

-----BEGIN-----
 The timeout in seconds an InnoDB transaction may wait for a row lock 
before giving up. The default value is 50 seconds. A transaction that 
tries to access a row that is locked by another InnoDB transaction will 
hang for at most this many seconds before issuing the following error:

ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting transaction
When a lock wait timeout occurs, the current statement is not executed. 
The current transaction is not rolled back.
-----END-----


So I wouldn't say that decreasing this value would change anything in
your case.
