3601	When running two or more instances of GHCi, persistent history is only kept for the first one	arnar		"The file `~/.ghc/ghci_history` maintains the command history for the first running GHCi instance. No persistent history is kept for concurrently running ghci processes. See #2050.

bash provides an option of setting `shopt -s histappend`, which makes all bash instances share the same history file. Perhaps writing to the same file would be somewhat silly in the case of GHCi, but writing to .ghci_history.2 or similar could be one solution.

Alternatively, a command within GHCi to dump the current instance's command history to a file would work also."	feature request	new	normal	_|_	GHCi	6.10.4		ghci history		Unknown/Multiple	Unknown/Multiple	Other
