calling to FS.syncfs in Worker for improving rendering frame rate

[aharondavid]

To improve rendering frame rate on the main thread , I thought to move a call to FS.syncfs from the Main Thread to a Worker thread.
I call to FS.syncfs on every IDBFS file close.
but, is FS.syncfs safe thread? should I lock\unlock calling to FS.syncfs in worker ?

The emscripten filesytem is implemented on the main thread (at least in its current state, I think WASMFS is changing that). That means that all FS operations are proxied back the main thread. It also means that accessing the FS object from JavaScript on a worker simply doesn't work. The FS object (at the least the one exposed to native code) lives on the main thread only.

Ok, thanks.
