canShareDiskPaths: Boolean
Indicates whether the buffer may share a spill file with other buffers.
Indicates whether the buffer may share a spill file with other buffers. If false then the spill file will be automatically removed when the buffer is freed. If true then the spill file will not be automatically removed, and another subsystem needs to be responsible for cleaning up the spill files for those types of buffers.
