Using backticks ( `cmd`) hang child processes?

Ruby
1

Hi All,

i execute small ruby code:

puts(“in x\n”)
x = Thread.current
y = Thread.start {
i = 0;
while (1)
puts(“in y #{i}\n”)
STDOUT.flush()
i +=1;
end
puts(“in y1\n”)
STDOUT.flush()

  }
 puts("in x1\n")
 STDOUT.flush()

system(“sleep 5”)

 `sleep 5`

it seems that using sleep 5 cause y thread to hang.
if i change in and remark sleep 5 and unmark system command , it seems
to work just fine.

is it a bug?
is this is the righr behavior?
i’m using a little bit old version of ruby (1.8.2) but still, i didn’t
find any post about this issue.

i’ll happy to hear any comment about this issue.

Thanks,
Noam.
