connectionTimeout is not timing out long client write times in JBossWeb

Issue

• Thread dumps show threads stalling for some time in socket writes to clients in JBossWeb, for example:

  "127.0.0.1-8080-1" daemon prio=10 tid=0x0000000057503800 nid=0x7b37 runnable [0x00000000456fa000]
     java.lang.Thread.State: RUNNABLE

• This Socket write state appears to last much longer than our connector's configured connectionTimeout. Why is the connectionTimeout not limiting the length of these socket writes?
