bug report #18

Closed bflagg closed 2 years ago

bflagg commented 2 years ago

https://github.com/objecthub/swift-lispkit/blob/f2d5a8ac8d606da108d938c4f1d68b4687bd0d28/Sources/LispKit/IO/TextOutput.swift#L152

Calling flush() here seems to cause a double lock() error.

Recommend call flushBuffer() instead.
