Adam --

I honestly don't think that what you think is happening is actually
happening. I think what might be more realistic is that one of your
stored procedures has started scanning a table, or acquiring a
long-lived lock, causing the others to slow down. Or perhaps something
else is acquiring a lock, slowing up your procedures. 1:30 to
recompile a query plan is an absolutely enormous amount of time. Keep
in mind that the time that it takes to run your query may vary by the
inputs that are passed to it. Have you run SQL Server Profiler and run
a trace? Look for large amounts of reads and writes associated with
the long duration of your stored procedures.
