Set the memory threshold under which system failure will be notified.

This value may be dynamically modified while the system is running. The default is 1048576
bytes. This can be set using the system property
<code>gemfire.SystemFailure.chronic_memory_threshold</code>.

@param newVal threshold in bytes
@return the old threshold
