Description:
Set SendBufferMemory and ReceiveBufferMemory to 20M.
An API generated inserts (2500 in a batch). The 2500 operations were executed sucessfully but the api did not get an answer. Something is strange using large buffers...

How to repeat:
later

Suggested fix:

Could not reproduce using latest 5.0-ndb tree (granted, on ppc not x86_64).

Is there example API code to trigger this? If so, it would be useful. Has it been reproduced anywhere else but x86_64?

I can try on x86_64 with appropriate test case.
