+ * This file provides a global hashtable for tracking `wasi-libc`-managed file
+ * descriptors.
+ *
+ * WASI Preview 2 has no notion of file descriptors and instead uses unforgeable
+ * resource handles.  Moreover, there's not necessarily a one-to-one
+ * correspondence between POSIX file descriptors and resource handles (e.g. a
+ * TCP connection may require separate handles for reading, writing, and polling
+ * the same connection).  We use this table to map each POSIX descriptor to a
+ * set of one or more handles.
+ *
+ * As of this writing, we still rely on the WASI Preview 1 adapter
+ * (https://github.com/bytecodealliance/wasmtime/tree/main/crates/wasi-preview1-component-adapter)
+ * to manage non-socket descriptors, so currently this table only tracks TCP and
+ * UDP sockets.  We use the adapter's `adapter_open_badfd` and
+ * `adapter_close_badfd` functions to reserve and later close descriptors to
+ * avoid confusion (e.g. if an application tries to use Preview 1 host functions
+ * directly for socket operations rather than go through `wasi-libc`).
+ * Eventually, we'll switch `wasi-libc` over to Preview 2 entirely, at which
+ * point we'll no longer need the adapter.  At that point, all file descriptors
+ * will be managed exclusively in this table.
