If I understood it well enough to document properly, I would have
fixed it :-)

All I know is that some callers have problems, but most do not.
Blaming the buffered/unbuffered state of the pipe is just a guess
based on Johannes' earlier comments in x11.trm, but I cannot
confirm this is the crucial difference.

The same for your just-reported problem under OS2.  I have no
idea exactly what is different in the environment, but something
obviously is making the communication channel lose synchronization.

The best thing may be to add a -noXfeedback option to the
command line, and document that it should be used in case
of problems such as the ones seen with awk scripts or OS2.=20
