-When this function is called to unpause receiving, the chance is high that you
-will get your write callback called before this function returns.
+When this function is called to unpause receiving, the write callback might
+get called before this function returns to deliver cached content. When
+libcurl delivers such cached data to the write callback, it will be delivered
+as fast as possible, which may overstep the boundary set in
+\fICURLOPT_MAX_RECV_SPEED_LARGE(3)\fP etc.
The \fBhandle\fP argument identifies the transfer you want to pause or
