Yes, just to make it explicit, this will block until the pipe closes, i.e.,
the external program terminates.  This can be a long time, depending on the
external program.  :)

This can be avoided by reading single lines (which blocks until a full line
is available), or by specifying a number of bytes to read (which blocks
until that many bytes are available).  I think there is also an optional
timeout, but it's been a while since I poked around with popen*() ...

(I see that you already found a solution, but I wanted to post this for the
benefit of anyone else who might be following along...)
