Danail Branekov 7b3e0bcf29 Ensure the scratch pipe is read during ExportBPF ...

There is a potential deadlock where the ExportBPF method call writes to
a pipe but the pipe is not read until after the method call returns.
ExportBPF might fill the pipe buffer, in which case it will block
waiting for a read on the other side which can't happen until the method
returns.

Here we concurrently read from the pipe into a buffer to ensure
ExportBPF will always return.
