Description of problem:
'gs' hangs up executing 'gs -q -sDEVICE=pdfwrite  -
sOutputFile=archoverview.pdf - -c quit < gspipe.input'
Looking at the system trace I've found it's because of reading 
from /dev/random:
strace -o gs.log gs -q -sDEVICE=pdfwrite  -
sOutputFile=archoverview.pdf - -c quit < gspipe.input
Here is a piece of qs.log:
open("/dev/random", O_RDONLY)           = 13
fstat64(13, {st_mode=S_IFCHR|0644, st_rdev=makedev(1, 8), ...}) = 0
ioctl(13, TCGETS, 0xbfff9318)           = -1 EINVAL (Invalid argument)
1, 0) = 0xb75e5000
read(13, 0xb75e5000, 4096)              = ? ERESTARTSYS (To be

Initially the problem came up from the epstopdf PERL script (package

But it isn't reproducible on another one.

Steps to Reproduce:
