Actually, the OP already has IO::Handle loaded (via IO::Socket via IO::Socket::INET), so it's free for him.

For others, it has a one-time cost of 100ms. 

>perl -le"use Time::HiRes qw( time ); $stime=time; require IO::Handle;
+ $etime=time; print $etime-$stime;"

>perl -le"use Time::HiRes qw( time ); $stime=time; require IO::Handle;
+ $etime=time; print $etime-$stime;"

>perl -le"use Time::HiRes qw( time ); $stime=time; require IO::Handle;
+ $etime=time; print $etime-$stime;"

It's up to them if that's acceptable or not. If it's not, I suggest copying autoflush out of IO::Handle and call it as follows rather than twiddling with select and $| directly. 

autoflush(HANDLE, 1);
