You said this app was not using MySQL. Is it using Oracle? if so,
ok. Otherwise, why did your trace wander through the Oracle client
libraries? 

(I spent a lot of time one day trying to trace some Oracle library
oddities. The very un-Linux like solution of rebotting the VM fixed
things but I am now quite leary of unexplained Oracle detours. There
is also a very odd interaction with LDAP and the Oracle LDAP libraries
- http://lists.rubyonrails.org/pipermail/rails/2006-April/032583.html.)
