Description

When using ICompute.WithTimeout, the following scenario is possible:

• Timeout is reached, and Ignite interrupts compute job thread
• InterruptedException is thrown from the job code
• Ignite.NET tries to serialize the job result (exception) in BinaryUtils.WriteInvocationResult
• BinaryProcessor.PutBinaryTypes is called during the serialization
• Thread is interrupted, so metadata update fails with InterruptedException

As a result, instead of a simple timeout exception, there is a lot of cryptic errors in the log (see attachments).

Possible fixes:

• Handle InterruptedException as a special case in WriteInvocationResult so we don't need to send meta updates
• Do not interrupt binary meta updates
