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.
