freqman gets interface Ibalancer but then doesn't release it

[stanleybak]

in function find_entry_freq, freqman.c does

Ibalancer *balancer = mm->GetInterface(I_BALANCER, arena);

and then never releases it. This leads to errors when the modules are unloading since freqman can not unregister the interface because the reference count is nonzero.

EDIT: included a patch file to fix it. Run "patch freqman.c < freqman.patch"
