I didn't know you tie a file handle. Very cool!  

There's a wee bit of a performance hit using this method but well worth
the effort.

Benchmark: timing 10 iterations of normal, tied...
    normal:  9 wallclock secs ( 7.55 usr +  0.20 sys =  7.75 CPU) @
1.29/s (n=10)
      tied: 19 wallclock secs (17.41 usr +  0.16 sys = 17.56 CPU) @
0.57/s (n=10)

... Ooh and I can do this with any file handle. This opens up several
possibilities. My log files will never know what's hit them. Buahahahar!

Thanks for the great example.

Cheers

Alistair
