I think so :}. the "dllMain" function gets called on process attach and
detach, and also on thread attach and detach. dll loading doesn't
trigger dllMain, unless a dll is dependant on cygwin1.dll, and the
process that uses that dll _isn't_ dependant on cygwin1.dll - in which
case, dlsym is a moot point really().
