# While implementing fork-rate monitoring as per 
# http://word.bitly.com/post/74839060954/ten-things-to-monitor
# we discovered that we had Perl processes that were making large numbers
# of execve syscalls. Investigating further it appears Perl uses execvp
# from glibc which results in an execve syscall for each entry in the path
# when using `backticks`, sytem or open(FH, "exe|") etc.
# Compare this to bash that appears to avoid execvp and instead iterates
# $PATH using stat and a single execve syscall.
