Etherboot's implementation of PXENV_UDP_READ is and has always been
non-blocking. I don't see this problem when I try pxelinux from
syslinux-3.08-pre5 and current Etherboot CVS. The relevant routine,
pxenv_udp_read() in Etherboot's core/pxe_export.c, hasn't changed since
July last year.
You can debug this by defining -DTRACE_PXE when compiling Etherboot. This
will show you a call trace such as
