Some useful functions built on top of Unix.

'acall cmd wraps the result of Unix.open_process_full cmd into an object. It reads the full stdout and stderr of the subprocess before returning.
if provided, the generator or string is consumed and fed to the subprocess input channel, which is then closed.

val async_call :
?env:string array ->
('a, Buffer.t, unit, async_call_result) format4 ->
'aSpawns a subprocess, like call, but the subprocess's channels are line generators and line sinks (for stdin). if p is async_call "cmd", then p#wait waits for the subprocess to die. Channels can be closed independently.
