That's not completely unreasonable, but be aware that the server thread 
is entirely blocked whilst waiting for the exec to complete. If all 
threads in the pool are blocked, you'll have serious problems.

Basically: 10 seconds is a long to wait, so waiting even longer... I'm 
kind of curious what you're doing?

Anyway, enough people already get confused about this w.r.t. SQL/LDAP 
databases that are slow - the complain "the server is slow", when in 
fact the server is *blocked*. So you might want to surround this config 
option with BIG BOLD TEXT explaining this ;o)

Personally I think the option might be more generally useful for 
*decreasing* the timeout!
