Description of problem:
my_pollfd malloc() is unchecked, which could result in a segmentation fault.
Version-Release number of selected component (if applicable):
all current RHEL and Fedora versions
Steps to Reproduce:
The bug is not easily reproducible on demand, but could be responsible for some unexplained ypbind crashes.
An ill-timed malloc() failure would cause a segmentation fault.
The failure should be caught and reported, and the function should return gracefully to permit the calling application to handle it.
This was discovered by code inspection while troubleshooting ypbind.
