...and now i know why i got this error under HP-UX and not the other
operating systems. 
HP-UX defines EAGAIN and EWOULDBLOCK as different errors
#define EAGAIN          11      /* No more processes            */
#define EWOULDBLOCK             246     /* Operation would block */
while the others just mix them together. 
#define EAGAIN  11      /* Resource temporarily unavailable     */
#define EWOULDBLOCK     EAGAIN 
As EWOULDBLOCK is handled, an EAGAIN is handled too, while under HP-UX it
slips through.

Greetings from Munich,
Gerhard
