Is this a problem in pdf2ps also? When I ps2pdf'ed fossil.pdf and sent the
result to my HP4000, the printer hung. Had to power cycle it.

When page calls gs to display a postscript file which uses \r as a line
terminator (not \n or \r\n), deadlock ensues. Here's a correction (which
may also reduce the need for the '-P' option):
/sys/src/cmd/page/ps.c:429 a ps.c:430,434

> write(ps->gsfd, "\n", 1);
