issue with writing then immediately reading

[williamstein]

Serve and mount on the same computer as follows, with caching disabled to avoid it being relevant (it makes no difference though):

await require('.').serve({path:'/tmp/a', port:6000, host:'localhost'})

await require('.').mount({path:'/tmp/b', remote:"ws://localhost:6000", cacheTimeout:0})

Then try vi a; cat a in a terminal, with editing the file slightly, then doing ZZ to exit:

/tmp/b/git$ vi a; cat a
/tmp/b/git$ 

Note that the output is empty for a moment, i.e., a is blank. If instead you insert a second sleep in then it works fine:

/tmp/b/git$ vi a; sleep 1; cat a
proper content
