.SH NAME
tapset::guru-delay \- systemtap guru-delay tapset
 
.SH DESCRIPTION

 Functions in the guru-delay tapset allow a probe handler to insert
 deliberate delays.  This is sometimes useful as a fault-injection
 aid.  Due to its likelihood of interference with the kernel, guru
 mode is required, and overload-prevention is suppressed.
