As I understand the purpose of 'maxWriteQueueSize' is throttling (avoid file
writer overload when there are to many writes), it defenetely should not case
hangs. We can fix it this way: if value size is large than 'maxWriteQueueSize'
print warning that this paremeter should be increased, then such large values
should just wait when write queue is empty.

Dmitriy, can we automatically increase the queue size in this case? This
definitely should not hang. At the very least we should throw an exception with
a proper message, but this is not good either because the fix will require full
cluster restart.

Hi [~vkulichenko], i found problem. It happened because you try to add byte
buffer with size more than write thread can process to swap file.
Option in FileSwapSpaceSpi name DFLT_QUE_SIZE, by deffault 1024 * 1024, you
can set more if you need.
