-----------
Reduce memory usage when sending SharedBuffer across IPC
https://bugs.webkit.org/show_bug.cgi?id=248301
rdar://102201837
Pack small SharedBuffers across a single allocated SharedMemory.
A threshold of 4kB has been chosen through educated guesses.
Have URLSchemeTaskDidReceiveData use SharedBuffer when sending data to the
content
process rather than a SharedBufferReference. The primary use of a
SharedBufferReference
is to keep ownership of the allocated memory to the sending process. There's no
such requirement here.
Fly-by improvement, only perform a single memory allocation when passing a
FragmentedShared made of multiple segments
on GTK and WPE platfom.
