Have you ported much of druntime to Uclibc?  It currently assumes 
Glibc on linux by default, so if there are differences between 
the way the two handle such signals, it can cause problems.  For 
example, the Android Java Runtime intercepts SIGUSR1/SIGUSR2 and 
doesn't run their signal handlers, so I had to work around that 
issue:

You may be running across a similar incompatibility, so I suggest 
you port all the version-dependent blocks of that module and its 
dependent modules first.
