Comment:
The RTS uses `SIGVTALRM` for its own purposes (scheduling and profiling).
This can cause certain system calls to return `EINTR`, but C library code
is supposed to handle `EINTR` properly and restart the system call. I
suspect that LDAP is not doing this, which would be a bug in LDAP.
You can work around the problem by passing `+RTS -V0` to GHC, although
note that this may have a negative impact on performance, because the
scheduler will context switch too often.
I'm closing the bug as `invalid` on the assumption that it is an LDAP bug.
If you think this is wrong, please re-open the ticket.
