8 * Using .in, .out, .err:
9 * - Specify 0 for no redirections (child inherits stdin, stdout,
10 * stderr from parent).
11 * - Specify -1 to have a pipe allocated as follows:
12 * .in: returns the writable pipe end; parent writes to it,
13 * the readable pipe end becomes child's stdin
14 * .out, .err: returns the readable pipe end; parent reads from
15 * it, the writable pipe end becomes child's stdout/stderr
16 * The caller of start_command() must close the returned FDs
17 * after it has completed reading from/writing to it!
18 * - Specify > 0 to set a channel to a particular FD as follows:
19 * .in: a readable FD, becomes child's stdin
20 * .out: a writable FD, becomes child's stdout/stderr
21 * .err > 0 not supported
22 * The specified FD is closed by start_command(), even in case
23 * of errors!

63 * can run in a thread without interfering with the caller.
