Waiting and waiting?by Gorby (Monk) |

Gorby has asked for the wisdom of the Perl Monks concerning the following question:
Hello wise monks. In my short program are these lines:
Would the can_read function cause the program to wait indefinitely until a handle is available for reading, or would these lines simply execute 5 times regardless of whether a handle is available for reading? Thanks in advance for your wisdom.
