[Bug: 21.5-b28] Crash in VM piping message to nonexistent command

I get a reliable crash when piping a message in VM to a nonexistent Unix command using vm-pipe-message-to-command. Here's a gdb backtrace: #0 0x90014ba8 in write () #1 0x00166720 in retry_write_1 (fildes=11, buf=0x2371800, nbyte=512, allow_quit=0) at sysdep.c:2755 #2 0x00106e50 in filedesc_writer (stream=0x20, data=0x2371800 ".21;
