Function WriteTransport.setWriteBufferLimits
Set the high- and low-water limits for write flow control.
These two values control when the protocol's pauseWriting() and resumeWriting() methods are called. If
specified, the low-water limit must be less than or equal to the
high-water limit.
The defaults are implementation-specific. If only the high-water limit
is given, the low-water limit defaults to an implementation-specific
value less than or equal to the high-water limit. Setting high to zero forces low to zero as well, and causes pauseWriting() to be called whenever the buffer becomes
non-empty. Setting low to zero causes resumeWriting() to be called only once the buffer is empty. Use of
zero for either limit is generally sub-optimal as it reduces
opportunities for doing I/O and computation concurrently.
