Can you give a more specific hint of which layer I should be looking at?
My thinking with putting the recovery on the VFS layer on the level of
principle is similar to how TCP makes IP seem reliable instead of
making the application worry about failures and on the practical level
it seemed harder to track down all higher-layer call sites that might
experience an exception than to mechanically wrap all methods on the
VFS layer.
