The key here is that back-quotes or $( command ) uses a pipe to get the output of the command.
Do you run a CPU-soaking background program such as SETI@home, Folding@home (the protein folding experiment) or fightAIDS@home (the AIDS drug discovery program)?
If so, you're seeing the result of the changes to how Cygin accesses pipes in 1.3.18.
I hope these changes will be perfected or backed out, since I don't want to give up running background CPU utilization software and in the long run I cannot afford to stop updating Cygwin (of course).

Update. I've further observed that while running whoami at the command-line returns a result immediately, running it inside a pair of back-tics "`" shows the blocking behavior. For instance, if I do this:
$ whoami
I get a result immediately.
However, if I do this:
$ echo `whoami`
It takes a good 5-10 seconds to print a value and return the prompt.
