_handle error at non-opencl platform when data is loaded (Trac #778)

[wpotrzebowski]

When data is loaded first time model computation raise _handle error:
!AttributeError: '!NoneType' object has no attribute '_handle'.

It is most like triggered by kernell.dll release() fucntion (line 336). I activated this function to make plugin models recompiled. It doesn't seem to cause any trouble apart from anoying message but needs to be fixed. This may be tcc issue only.

See also ticket SasView/sasview#798. If you can avoid evaluating the model twice then it won't try to compile twice and there will be no conflict and no need for an artificial sleep.
